Adult Dosage Normal Dosage Clobetasol Disorder of skin See Drug Consult reference: TOPICAL CORTICOSTEROIDS - DOSING GUIDELINES Clobetasol Propionate Topical application route Bullous pemphigoid 1) Another small trial reported the successful treatment of BULLOUS PEMPHIGOID (N=16) with a combination regimen of oral OXYTETRACYCLINE (500 milligrams (mg) 4 times daily), oral niacinamide (400 mg 3 times daily), and topical 0.5% clobetasol propionate cream. Once lesions began to heal, the oral doses were tapered over several weeks and clobetasol was replaced with a moisturizing emollient (Hornshuh et al, 1997). Disorder of skin, Corticosteroid responsive 1) For the treatment of inflammatory and pruritic manifestations of moderate to severe corticosteroidresponsive dermatoses, clobetasol cream, emollient, foam, gel, lotion, or ointment should be applied in a thin film to the affected area twice daily. The treated skin area should not be bandaged or otherwise covered or wrapped so as to be occlusive. Treatment should be limited to 2 consecutive weeks, and doses should not exceed 50 g/wk (or 50 mL/wk for the solution or 21 capfuls/week for the foam) [1] [2] [3] [4] [5] [6] . 2) For the treatment of inflammatory and pruritic manifestations of moderate to severe corticosteroidresponsive scalp dermatoses, clobetasol scalp application should be applied to affected areas twice daily, once in the morning and once at night. The maximum dose is 50 mL/wk for 2 weeks [3] . 3) Time to lesion clearance was shorter when clobetasol lotion was occluded with a hydrocolloid dressing than when unoccluded clobetasol ointment was used. Relapse rates were similar for the 2 treatments [19] . Plaque psoriasis (Mild to Moderate) 1) Olux(R) Foam a) For the treatment of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses, clobetasol foam should be applied in a thin film to the affected area twice daily. The treated skin area should not be bandaged or otherwise covered or wrapped so as to be occlusive. Treatment should be limited to 2 consecutive weeks and doses should not exceed 50 g/wk (or 50 mL/wk for the solution, or 21 capfuls/wk for the foam) [39] . Plaque psoriasis (Moderate to Severe) 1) Clobex(R) Lotion a) For the treatment of moderate to severe plaque psoriasis affecting up to 10% body surface area, apply Clobex(R) lotion to affected areas twice daily and rub in gently and completely; maximum dose and duration, 50 g (50 mL or 1.75 fluid ounces) per week for up to 4 consecutive weeks. Do not use with occlusive dressing. Treatment beyond 2 weeks should be limited to localized lesions of moderate to severe plaque psoriasis that have not sufficiently improved after the initial 2 weeks of treatment with clobetasol spray. If no improvement is seen within 2 weeks, reassess the diagnosis [6] . 2) Clobex(R) Spray a) For the treatment of moderate to severe plaque psoriasis affecting up to 20% body surface area, spray clobetasol on affected areas twice daily and rub in gently and completely; maximum dose and duration, 50 g (59 mL or 2 fluid ounces) per week for 4 consecutive weeks. Do not use with occlusive dressing. Treatment beyond 2 weeks should be limited to localized lesions of moderate to severe plaque psoriasis that have not sufficiently improved after the initial 2 weeks of treatment with clobetasol spray. If no improvement is seen within 2 weeks, reassess the diagnosis. Additional benefits beyond the initial 4 week treatment should be weighed against the risk of hypothalamic-pituitary-adrenal axis suppression [32] . 3) Temovate(R) E cream, emollient; Embeline(R) E emollient a) The recommended dose of Temovate(R) E cream or emollient and Embeline(R) E emollient for the treatment of moderate to severe plaque-type psoriasis is a thin layer applied topically to 5% to 10% of body surface area twice daily (maximum 50 g/wk). If using for more than 2 consecutive weeks, the benefit versus risk of hypothalamic-pituitary-adrenal axis (HPA) suppression should be evaluated. If improvement is not seen within 2 weeks, reassess the diagnosis. Treatment beyond 4 consecutive weeks is not recommended. Temovate(R) E cream should not be used with an occlusive dressing [1] [33] [34] . Scalp psoriasis (Moderate to Severe) 1) For the treatment of moderate to severe forms of scalp psoriasis, clobetasol shampoo, scalp solution, and Olux(R) foam should be applied to affected areas on a dry (not wet) scalp once daily in a thin film. It should be left in place 15 minutes before lathering and rinsing. The total dosage should not exceed 50 mL/wk. Treatment should be limited to 4 consecutive weeks and discontinued when control is achieved. Clobetasol shampoo is not to be used with occlusive dressings. Clobetasol shampoo should not be used on face, groin, or axillae; avoid contact with eyes and lips [43] [44] [39] . Vesicular stomatitis a) Clobetasol propionate mouthwash has been effectively used in the treatment of oral erosive lesions. The aqueous solution was composed of 0.05% clobetasol with nystatin 100,000 international units/mL. Ten mL of the solution was swished for 5 minutes 3 times per day and not swallowed [26] . Pediatric Dosage Normal Dosage Clobetasol Propionate Topical application route Disorder of skin, Corticosteroid responsive 1) For children 12 years and older with inflammatory and pruritic manifestations of moderate to severe corticosteroid-responsive dermatoses, clobetasol cream, emollient, foam, gel, or ointment should be applied in a thin film to the affected area twice daily. The treated skin area should not be bandaged or otherwise covered or wrapped so as to be occlusive. Treatment should be limited to 2 consecutive weeks and doses should not exceed 50 g/wk (or 50 mL/wk for the solution or 21 capfuls/wk for the foam) [1] [2] [3] [4] [5] . Plaque psoriasis (Mild to Moderate) 1) Olux(R) Foam a) For children 12 years and older with inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses, clobetasol foam should be applied in a thin film to the affected area twice daily. The treated skin area should not be bandaged or otherwise covered or wrapped so as to be occlusive. Treatment should be limited to 2 consecutive weeks and doses should not exceed 50 g/wk (or 50 mL/wk for the solution or 21 capfuls/wk for the foam) [39] . Plaque psoriasis (Moderate to Severe) 1) Temovate(R) E cream, emollient; Embeline(R) E emollient a) The recommended dose of Temovate(R) E cream and Embeline(R) E emollient in adolescents 16 years or older for the treatment of moderate to severe plaque-type psoriasis is a thin layer applied topically to 5% to 10% of body surface area twice daily (maximum 50 g/wk). If using for more than 2 consecutive weeks, the benefit versus risk of hypothalamic-pituitaryadrenal axis (HPA) suppression should be evaluated. If improvement is not seen within 2 weeks, reassess the diagnosis. Treatment beyond 4 consecutive weeks is not recommended. Temovate(R) E cream and Embeline(R) E emollient should not be used with an occlusive dressing [1] . The safety and efficacy of clobetasol (cream, emollient, gel, ointment, scalp solution) has not been not established in children under 12 years of age. Pediatric patients may demonstrate greater susceptibility to topical corticosteroidinduced hypothalamic-pituitary-adrenal axis suppression and Cushing syndrome than adult patients because of a larger skin surface area to body weight ratio [1] [2] [3] [4] [5] . Use of clobetasol shampoo, lotion, and topical spray in patients under 18 years of age is not recommended because of potential for hypothalamic-pituitary-adrenal axis suppression [44] [32] [6] . Scalp psoriasis (Moderate to Severe) a) Scalp solution, Olux(R) Foam 1) The recommended dose of scalp solution and Olux(R) foam in patients 12 years or older for the treatment of moderate to severe psoriasis of the scalp is to apply twice daily, no more than 50 mL/wk and no more than 2 consecutive weeks [43] [39] . PHARMACOKINETICS Onset and Duration A) Onset 1) Initial Response a) Dermatoses, topical: 10 to 21 days (highly individualized) [74] 2) Peak Response a) Dermatoses, topical: 2 months [75] B) Duration 1) Multiple Dose a) Psoriasis, topical: 23.3 days [74] to 4 weeks [76] ADME Absorption A) Bioavailability 1) Excessive topical application may result in systemic absorption which has been reported to suppress pituitary-adrenal function [77] [78] . 2) The concurrent use of occlusive dressings or application to inflamed skin may increase percutaneous absorption [79] [80] [81] [82] . 3) Following topical administration of 25 g applied to the whole body (excluding face, genitalia, and the arm from which blood was drawn), plasma CLOBETASOL levels rose rapidly during the first 3 hours. No CLOBETASOL could be detected in three patients (two with psoriasis; one with eczema) [83] .

Allergic contact dermatitis a) Allergic contact dermatitis has been reported with the application of topical corticosteroids such as clobetasol propionate. Patch testing is recommended to confirm diagnosis in lesions that fail to heal [52] [43] [49] [53] [51] [50] . b) In a multicenter study that included sites in Denmark, Portugal, Ireland, Belgium, France, Germany, Finland, Sweden, the Netherlands, and the United Kingdom (n=7238), 189 (2.6%) patients developed contact sensitivity to one or more topical corticosteroids. The following number of reactions occurred for each drug: (1) budesonide 0.1%, 100 reactions, (2) hydrocortisone-17-butyrate, 74 reactions, (3) clobetasol, 21 reactions, and (4) betamethasone valerate, 8 reactions. Since many patients had used corticosteroids previously, it is difficult to determine whether the sensitivity was to the tested agent or a cross-sensitivity to previously used agents. Sensitivity was determined via patch tests; all of the drugs were mixed in petrolatum except hydrocortisone which was mixed in ethanol [63] . c) Two cases of contact allergy to clobetasol propionate were reported, and confirmed by positive patch test [64] . A literature review of clobetasol propionate contact allergy was undertaken. It was shown that nearly half the subjects also had positive patch tests to at least one other topical corticosteroid formulation. Hypersensitivity should be suspected in cases of treatment failure or paradoxical worsening of dematosis. Two cases of contact dermatitis to clobetasol are reported and a review of the literature on corticosteroid-induced contact dermatitis provided [65] . A case of an allergic reaction to the 10% sorbitan sesquioleate present in the ointment was reported. There was no reaction to clobetasol propionate upon patch testing [66] .

Application site pigmentation changes a) Incidence: 1% [53] b) Pigmentation changes at the application site occurred in 1% of patients treated with clobetasol propionate topical spray (n=120) compared with 0% of patients treated with vehicle spray (n=120) in controlled clinical trials [53] . Application site reaction a) Incidence: 1.6% [52] b) Application-site reaction occurred in 1.6% of patients with atopic dermatitis and psoriasis treated with clobetasol propionate foam in controlled clinical studies (n=821). Most cases were rated as mild to moderate [52] . Asteatotic eczema a) Incidence: 2% [53] b) Eczema asteatotic was reported in 2% of patients treated with clobetasol propionate topical spray (n=120) compared with 0% of patients treated with vehicle spray (n=120) in controlled clinical trials [53] . Atrophic condition of skin a) Incidence: 1.9% to 4.2% [52] [50] b) Application-site atrophy occurred in 1.9% of patients with atopic dermatitis and psoriasis treated with clobetasol propionate foam in controlled clinical studies (n=821). Most cases were rated as mild to moderate [52] . c) Skin atrophy was reported in 4.2% of patients treated with clobetasol propionate lotion 0.05% twice daily for 2 or 4 weeks in pooled data from 2 clinical trials of patients with moderate to severe atopic dermatitis and plaque psoriasis [50] . d) In clinical studies, skin atrophy was reported with topical application of clobetasol propionate cream and ointment [49] . e) Skin atrophy has commonly been reported in patients treated with clobetasol propionate shampoo in clinical studies [51] . f) Application of clobetasol 0.05% ointment daily for 16 days resulted in skin atrophy (eg, decrease in skin thickness of about 12%). Continued intermittent administration at intervals of every 5, 7, 10, or 14 days resulted in a plateau effect on skin atrophy. With longer intervals between applications, skin thickness increased but not back to baseline. This study was designed to evaluate the effect of continuous followed by intermittent application of a potent topical corticosteroid on skin atrophy. In dermatology, continuous application for a few weeks is used to induce remission followed by intermittent application to maintain a remission [62] . Burning sensation a) Burning and stinging sensation was reported in 29 of 294 patients with topical application of clobetasol propionate solution for the scalp [43] b) In a clinical studies, burning sensation was reported in 1.8% of patients with the topical application of clobetasol propionate gel [49] . c) In clinical studies, burning and stinging sensation was reported in 1% of patients with the topical application of clobetasol propionate cream [49] . d) In clinical studies, burning sensation was reported in 0.5% of patients with the topical application of clobetasol propionate ointment [49] . e) Burning at the application site occurred in 40% of patients treated with clobetasol propionate topical spray (n=120) compared with 47% of patients treated with vehicle spray (n=120) in controlled clinical trials [53] . f) Burning and stinging was reported in patients treated with clobetasol propionate lotion 0.05% in controlled clinical trials [50] . g) Burning and stinging was reported with the topical application of clobetasol propionate shampoo in clinical studies [51] . Dermatitis a) Dermatitis occurred in 1 of 294 patients with the topical application of clobetasol propionate solution for the scalp [43] . Discomfort, Skin a) Incidence: 1.3% [50] b) Skin discomfort was reported in 1.3% of patients treated with clobetasol propionate lotion 0.05% twice daily for 2 or 4 weeks in pooled data from 2 clinical trials of patients with moderate to severe atopic dermatitis and plaque psoriasis [50] . Dry skin a) Incidence: 1% to 2% [53] [50] b) Dry skin was reported in 1% of patients treated with clobetasol propionate lotion 0.05% twice daily for 2 or 4 weeks in pooled data from 2 clinical trials of patients with moderate to severe atopic dermatitis and plaque psoriasis [50] . c) Dryness at the application site occurred in 2% of patients treated with clobetasol propionate topical spray (n=120) compared with 0% of patients treated with vehicle spray (n=120) in controlled clinical trials [53] . d) Dry skin has commonly been reported in patients treated with clobetasol propionate shampoo in clinical studies [51] . Erythema a) Erythema was reported in patients treated with clobetasol propionate lotion 0.05% in controlled, clinical trials [50] .

Perioral dermatitis a) Perioral dermatitis has been reported with the application of topical corticosteroids such as clobetasol propionate [52] [43] [49] [53] [51] [50] . Pruritus a) Incidence: 0.5% to 3% [49] [51] [53] b) Itching and tightness of the scalp was reported in 1 of 294 patients with topical application of clobetasol propionate solution for the scalp [43] . c) In clinical studies, itching was reported with the topical application of clobetasol propionate cream [49] . d) In clinical studies, itching was reported in 0.5% of patients with the topical application of clobetasol propionate ointment [49] . e) Pruritus at the application site occurred in 3% of patients treated with clobetasol propionate topical spray (n=120) compared with 3% of patients treated with vehicle spray (n=120) in controlled clinical trials [53] . f) Pruritus was reported during clinical trials in patients treated with clobetasol propionate lotion 0.05% [50] . Psoriasis a) Generalized pustular psoriasis associated with withdrawal of clobetasol therapy occurred in psoriatic patients receiving more than 50 g/wk for 2 weeks [67] . b) Two cases of general pustular psoriasis were reported following withdrawal of topical clobetasol propionate therapy for psoriasis . Both patients showed initial improvement followed by a worsening of the psoriasis and an increase in inflammation and pustule formation. In the first case, clobetasol therapy had been discontinued for 6 weeks when psoriasis showed widespread annular lesions and pustulation. In the second case, psoriasis flared up with extensive pustulation 1 month after clobetasol had been stopped. Active pustulation stopped at 2 and 3 weeks, respectively, and methotrexate/azathioprine therapy produced further improvement [68] . c) Clobetasol propionate 0.1% was applied topically in a dose of approximately 40 g/day to a 61-year-old woman with psoriasis. Following initial improvement in the patient's condition, pustules formed, which spread outwards from flexures. They were associated with erythroderma, intermittent fever, rigors, and gross local edema. Adrenal suppression also occurred [69] .

Telangiectasia a) Incidence: 3.2% [50] b) Telangiectasia was reported in 3.2% of patients treated with clobetasol propionate lotion 0.05% twice daily for 2 or 4 weeks in pooled data from 2 clinical trials of patients with moderate to severe atopic dermatitis and plaque psoriasis [50] . c) In clinical studies, telangiectasia has occurred with the topical application of clobetasol propionate ointment [49] . d) Telangiectasia has commonly been reported in patients treated with clobetasol propionate shampoo in clinical studies [51] . Tingling of skin a) Tingling occurred in 2 of 294 patients with the topical application of clobetasol propionate solution for the scalp [43] . Urticaria a) Urticaria has commonly been reported in patients treated with clobetasol propionate shampoo in clinical studies [51] . Endocrine/Metabolic Effects Clobetasol Propionate Cushing's syndrome a) Cushing syndrome has been reported following the systemic absorption of topical corticosteroids such as clobetasol propionate [52] [43] [49] [53] [51] [50] and was reported during postmarketing surveillance of 0.05% clobetasol propionate lotion and shampoo [50] [51] . Delayed growth and development a) Linear growth retardation and delayed weight gain have been reported in children treated with topical corticosteroids such as clobetasol propionate [50] [52] [43] [49] [53] [51] . Diabetes mellitus a) The unmasking of latent diabetes mellitus has been reported following systemic absorption of topical corticosteroids such as clobetasol propionate [52] . Hyperglycemia a) Hyperglycemia has been reported following the systemic absorption of topical corticosteroids such as clobetasol propionate [50] [52] [43] [49] [53] [51] . Secondary hypocortisolism a) Summary 1) Reversible hypothalamic-pituitary-adrenal (HPA) axis suppression has occurred following systemic absorption of topical corticosteroids [52] [43] [49] [53] [51] [50] . An increased incidence of HPA axis suppression may be observed with use of the more potent corticosteroids, use of medication over a large surface area, prolonged use, the addition of occlusive dressings, and coexisting hepatic failure [52] [50] [53] [51] . Additionally, higher skin surface to body mass ratios place pediatric patients at higher risk for HPA axis suppression than adults [52] [43] [49] [53] [51] [50] . Periodic evaluation for HPA axis suppression may be necessary. The diagnosis of HPA axis suppression warrants gradual withdrawal of clobetasol propionate therapy, decreased dosage, or substitution of a less potent steroid. Following discontinuation of the drug, recovery of the HPA axis is usually prompt and complete. Rarely, steroid withdrawal symptoms occur and require supplemental systemic corticosteroids [52] [43] [49] [53] [51] [50] . b) Incidence: adult, 15% to 20% [52] [53] ; pediatric, 42% to 47% [52] [51] c) Adults 1) In a clinical study of patients with atopic dermatitis covering at least 30% of the body, HPA axis suppression occurred in 16.2% of patients (6 of 37) 12 years or older following 2 weeks of topical clobetasol propionate foam treatment applied twice daily. Cortisol levels of all HPA axissuppressed patients had returned to normal upon testing 4 weeks after treatment. HPA axis suppression included serum cortisol levels of 18 mcg/dL or less, as measured 30 minutes post-cosyntropin stimulation [52] . 2) HPA suppression has occurred with clobetasol propionate 0.05% cream, gel, or ointment doses as low as 2 g daily [43] [49] . 3) In a clinical study of patients with moderate to severe atopic dermatitis, adrenal suppression occurred in 5 of 9 patients following 2 weeks of topical clobetasol propionate lotion treatment. Suppression remained after 7 days in 1 of 3 patients who had follow-up testing [50] . 4) In a clinical study of patients with moderate to severe plaque psoriasis, adrenal suppression occurred in 8 of 10 patients following 4 weeks of topical clobetasol propionate lotion treatment. Suppression remained after 8 days in 1 of 2 patients who had follow-up testing [50] . 5) In a clinical study of patients with plaque psoriasis covering at least 20% of the body, HPA axis suppression occurred in 15% of patients (2 of 13) following 4 weeks of topical clobetasol propionate spray treatment applied twice daily. Cortisol levels of HPA axis-suppressed patients returned to normal after therapy stopped. HPA axis suppression included serum cortisol levels of 18 mcg/dL or less, as measured by the cosyntropin stimulation test [53] . 6) In a clinical study of patients with plaque psoriasis covering at least 20% of the body, HPA axis suppression occurred in 19% (4 of 21) and 20% (3 of 15) of patients treated for 2 and 4 weeks, respectively, with topical clobetasol propionate 0.05% spray treatment applied twice daily. Cortisol levels of HPA axis-suppressed patients returned to normal after therapy stopped. HPA axis suppression included serum cortisol levels of 18 mcg/dL or less, as measured by the cosyntropin stimulation test [53] . 7) Adrenal suppression was also reported during postmarketing surveillance of 0.05% clobetasol propionate lotion and shampoo [50] [51] . 8) Clobetasol 0.05% cream 3 times daily for 2 weeks produced suppression of morning cortisol concentrations (below 5 mcg/dL) in significantly more patients than those receiving fluocinonide 0.05% cream [54] . 9) Adrenal suppression caused by 3 ointments was compared in 24 normal male volunteers. Results demonstrated that clobetasol propionate 0.05% produced greater adrenal suppression than did diflorasone diacetate PG 0.05%, which produced greater suppression than did fluocinonide 0.05%. Adrenal suppression caused by fluocinonide 0.05% was about equal to placebo. The drugs were applied to about 75% of the body surface area once a day for 6 days at a dose of 10 g/m(2). During the medication phase, serum cortisol levels for clobetasol patients were as low as 1 mcg/dL (normal 5 to 10 mcg/dL) [55] . 10) Absorption of clobetasol propionate was shown to be significantly reduced by the use of d-N-butyl-adipate (instead of propylene glycol) as a vehicle for the ointment and cream, without significantly affecting topical vasoconstrictor potency. Administration of the new preparation at 15 g daily for 12 days did not depress plasma cortisol levels; however, marked depression was observed with the propylene glycol preparation (Dermovate(R)) [56] . 11) In a double-blind, vehicle-controlled study of clobetasol 0.05% scalp application in 378 patients, subnormal morning plasma cortisol values were reported in 5% of patients receiving the active drug and in 5% of those receiving the vehicle alone. A 50% or greater decrease in morning cortisol occurred in the patients receiving the active drug after 2 weeks of therapy vs 5% in the control group. Most of the depressed plasma cortisol levels returned to normal even during continued treatment. Within 1 week of discontinuing therapy, all patients had normal plasma cortisol levels [57] . d) Pediatrics 1) HPA axis suppression occurred in 47% of patients (7 of 15) ages 6 to 11 years following 2 weeks of topical clobetasol propionate foam treatment applied twice daily. Serum cortisol levels in all HPA axis-suppressed patients returned to normal 4 weeks after treatment [52] . 2) HPA axis suppression occurred in 42% of patients (5 of 12) ages 12 to 17 years following 4 weeks of topical clobetasol propionate shampoo treatment applied once daily. One HPA axis-suppressed patient who was tested after treatment recovered after 2 weeks [51] . 3) Adrenal suppression occurred in 9 of 14 patients ages 12 to 17 years following 2 weeks of topical clobetasol propionate lotion treatment twice daily for atopic dermatitis covering at least 20% of the total body surface area. One of 4 patients who were retested after treatment remained suppressed after 2 weeks [50] . Immunologic Effects Clobetasol Propionate Immune hypersensitivity reaction a) Corticosteroids, because of their anti-inflammatory effects, often mask the clinical signs of contact dermatitis to a corticosteroid preparation. Corticosteroid-sensitive patients usually present with symptoms of chronic eczema which fails to respond to therapy. Due to the reported failure of therapy, the physician often prescribes a more potent corticosteroid which may cause additional side effects and possibly systemic effects. Topical corticosteroids also often mask patch-test reactions obtained with the corticosteroid molecules [71] . Musculoskeletal Effects Clobetasol Propionate Osteoporosis a) A case of osteonecrosis of both femoral heads and osteoporosis occurred in a 51-year-old woman following the long-term use of 0.05% clobetasol propionate ointment for psoriasis of 26 years. The patient had used an average of 60 g/week for 5 years and was reported to have never received systemic corticosteroids and had no clinical evidence of hyperadrenocorticism. Plasma cortisol at 8 am was normal. However, the patient also had a significant past history of alcohol abuse which may have contributed to the osteonecrosis [70] . Neurologic Effects Clobetasol Propionate Headache a) Incidence: 1.8% [51] b) Headache occurred in 1 of 294 patients with the topical application of clobetasol propionate solution for the scalp [43] . c) In phase 2 and 3 clinical trials in patients with moderate to severe scalp psoriasis, headache occurred in 1.8% of patients treated with clobetasol propionate shampoo (n=558) compared with 0.8% of patients treated with vehicle shampoo (n=127) [51] . Intracranial hypertension, acute a) Intracranial hypertension has been reported in children treated with topical corticosteroids, such as clobetasol propionate, manifesting with headaches, bilateral papilledema, and bulging fontanelles [52] [43] [49] [53] [51] [50] . Numbness of finger a) Numbness of fingers was reported with the application of clobetasol propionate topical ointment in controlled clinical studies [49] . Ophthalmic Effects Clobetasol Propionate Eye irritation a) Eye irritation occurred in 1 of 294 patients with topical application of clobetasol propionate solution for the scalp [43] . Raised intraocular pressure a) Elevated intraocular pressure has occurred within days to weeks after starting topical corticosteroid therapy and is generally reversed within 1 to 2 months after discontinuing the corticosteroid. The onset may be very rapid and severe, resembling that of acute glaucoma. Low-potency corticosteroids (hydrocortisone, dexamethasone, flumethalone, prednisolone, methylprednisolone) are recommended for use on the eyelid and periorbital area, with discontinuation of therapy following clearing of the dermatological condition [58] . b) Topical application of corticosteroids to the eye may induce intraocular pressure elevation in approximately 30% of patients receiving this type of therapy [59] . This condition most frequently develops following application of solutions. Ocular penetration of topical corticosteroid ointments to the eyelids has resulted in glaucomatous changes [60] [61] . Renal Effects Clobetasol Propionate Glycosuria a) Glucosuria has been reported following systemic absorption of topical corticosteroids such as clobetasol propionate [50] [43] [49] [53] [51] . Respiratory Effects Clobetasol Propionate Nasopharyngitis a) Incidence: 5% [53] b) Nasopharyngitis occurred in 5% of patients treated with clobetasol propionate topical spray (n=120) compared with 3% of patients treated with vehicle spray (n=120) in controlled clinical trials [53] . Streptococcal pharyngitis a) Incidence: 1% [53] b) Streptococcal pharyngitis occurred in 1% of patients treated with clobetasol propionate topical spray (n=120) compared with 0% of patients treated with vehicle spray (n=120) in controlled clinical trials [53] . Upper respiratory infection a) Incidence: 8% [53] b) Upper respiratory tract infection occurred in 8% of patients treated with clobetasol propionate topical spray (n=120) compared with 2% of patients treated with vehicle spray (n=120) in controlled clinical trials [53] . Other Clobetasol Propionate Secondary infection a) Secondary infections have been reported with the application of topical corticosteroids such as clobetasol propionate. If an infection develops, treat with an appropriate antimicrobial or antifungal medication; therapy with clobetasol propionate may need to be suspended until the infection is controlled [52] [43] [49] [53] [51] [50] . b) Infections and infestations have occurred in 14% of patients treated with clobetasol propionate topical spray (n=120) compared with 10% of patients treated with vehicle spray (n=120) in controlled clinical trials [53] . Teratogenicity/Effects in Pregnancy/Breastfeeding A) Teratogenicity/Effects in Pregnancy 1) U.S. Food and Drug Administration's Pregnancy Category: Category C (All Trimesters) a) Either studies in animals have revealed adverse effects on the fetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the fetus. See Drug Consult reference: PREGNANCY RISK CATEGORIES 2) Crosses Placenta: Unknown 3) Clinical Management a) There are no adequate or well controlled studies of clobetasol use during human pregnancy. Currently there are no data on the use of clobetasol in pregnant women and the safe use of topical corticosteroids in pregnancy has not been established. The effects, if any, on the developing fetus are unknown. During animal studies, administration of subQ clobetasol, at doses up to 0.003 times the recommended human topical dose, resulted in fetotoxicity and teratogenic effects. Clobetasol has a greater teratogenic potential than some less potent steroids. Due to the lack of human safety information, the manufacturer recommends the use of clobetasol during pregnancy only if the potential maternal benefit outweighs the potential fetal risk [1] . 4) Literature Reports a) There are no adequate or well controlled studies of clobetasol use in human pregnancy. During animal studies, administration of corticosteroids, at relatively low levels, has resulted in teratogenic effects. Administration of subQ clobetasol 0.03 to 1 mg/kg (approximately 0.01 and 0.33 times the human topical dose, respectively) to mice resulted in fetotoxicity and teratogenicity, including cleft palate and skeletal abnormalities. In pregnant rabbits, administration of clobetasol 3 and 10 mcg/kg (approximately 0.001 and 0.003 times the human topical dose, respectively) resulted in teratogenic effects such as cleft palate, cranioschisis, and skeletal abnormalities [1] . B) Breastfeeding 1) Micromedex Lactation Rating: Infant risk cannot be ruled out. a) Available evidence and/or expert consensus is inconclusive or is inadequate for determining infant risk when used during breastfeeding. Weigh the potential benefits of drug treatment against potential risks before prescribing this drug during breastfeeding. 2) Clinical Management a) Lactation studies with clobetasol have not yet been conducted. No reports describing the use of clobetasol during human lactation are available and the effects on the nursing infant from exposure to the drug in milk are unknown. Systemic corticosteroids are detectable in small quantities in breast milk and may cause adverse effects (eg, growth suppression). It is unknown if topical corticosteroid administration can result in systemic absorption. Because many drugs are excreted in human milk, the manufacturer recommends the use of caution when prescribing topical corticosteroids to a nursing woman [1] . Drug Interactions Drug-Drug Combinations Glycerol Phenylbutyrate 1) Interaction Effect: increased plasma ammonia levels 2) Summary: Use of a corticosteroid may cause increased plasma ammonia levels due to the breakdown of body protein. Closely monitor ammonia levels with concurrent use of glycerol phenylbutyrate and corticosteroids [72] . 3) Severity: moderate 4) Onset: unspecified 5) Substantiation: theoretical 6) Clinical Management: The use of a corticosteroid may cause increased plasma ammonia levels from the breakdown of body protein. If coadministration of glycerol phenylbutyrate and a corticosteroid is required, closely monitor ammonia levels [72] . 7) Probable Mechanism: increased protein catabolism by corticosteroids Pixantrone 1) Interaction Effect: decreased exposure of pixantrone 2) Summary: Concurrent administration of pixantrone (a Pglycoprotein (P-gp) substrate) and a P-gp inducer may decrease the exposure of pixantrone. If concurrent administration of pixantrone and a P-gp inducer is required, additional caution is recommended [73] . 3) Severity: major 4) Onset: unspecified 5) Substantiation: theoretical 6) Clinical Management: Concurrent administration of pixantrone (a P-glycoprotein (P-gp) substrate) and a P-gp inducer may decrease the exposure of pixantrone. If concurrent administration of pixantrone and a P-gp inducer is required, additional caution is recommended [73] . 7) Probable Mechanism: induction of P-glycoprotein-mediated efflux transport of pixantrone CLINICAL APPLICATIONS Monitoring Parameters A) Clobetasol Propionate 1) Therapeutic a) Physical Findings 1) Corticosteroid-Responsive Dermatosis a) Reduced inflammation and/or pruritus may indicate efficacy. 2) Moderate-to-Severe Plaque-Type Psoriasis a) Improvement in lesions and/or control of disease may indicate efficacy. 2) Toxic a) Laboratory Parameters 1) Consider periodic evaluation for adrenal suppression (eg, adrenocorticotropic hormone (ACTH) stimulation test, morning cortisol level), especially in pediatric patients, and when used over large surface areas, over prolonged periods, under occlusion, on an altered skin barrier, and in patients with liver failure [1] .

Place In Therapy A) Clobetasol propionate is the most potent corticosteroid available in the United States [101] [12] . It has been more effective than fluocinonide, betamethasone, and halcinonide in the treatment of psoriasis and eczema. From results of clinical trials, clobetasol has been shown to be very effective. It should be considered for admission to hospital formularies for the treatment of severe and/or refractory dermatoses. B) Guidelines for the selection and use of topical corticosteroids have been developed by a Committee of the American Academy of Dermatology [102] . Low-to-medium potency agents are usually effective for treating thin, acute, inflammatory skin lesions; whereas, high or super-potent agents are often required for treating chronic, hyperkeratotic, or lichenified lesions. Since the stratum corneum is thin on the face and intertriginous areas, low-potency agents are preferred but a higher potency agent may be used for 2 weeks. Because the palms and soles have a thick stratum corneum, high or super-potent agents are frequently required. Low potency agents are preferred for infants and the elderly. Infants have a high body surface area to weight ratio; elderly patients have thin, fragile skin. C) Guidelines for the selection and use of topical corticosteroids have been developed by a Committee of the American Academy of Dermatology [102] . The vehicle in which the topical corticosteroid is formulated influences the absorption and potency of the drug. Ointment bases are preferred for thick, lichenified lesions; they enhance penetration of the drug. Creams are preferred for acute and subacute dermatoses; they may be used on moist skin areas or intertriginous areas. Solutions, gels, and sprays are preferred for the scalp or for areas where a non- oil-based vehicle is needed. D) Guidelines for the selection and use of topical corticosteroids have been developed by a Committee of the American Academy of Dermatology [102] . In general, super-potent agents should NOT be used for longer than 3 weeks unless the lesion is limited to a small body area. Medium-to-high potency agents usually cause only rare adverse effects when treatment is limited to 3 months or less, and use on the face and intertriginous areas are avoided. If long-term treatment is needed, intermittent versus continuous treatment is recommended. E) Guidelines for the selection and use of topical corticosteroids have been developed by a Committee of the American Academy of Dermatology [102] . Most preparations are applied once- or twice-daily. More frequent application may be necessary for the palms or soles because the preparation is easily removed by normal activity and penetration is poor due to a thick stratum corneum. Every-other-day or weekend-only application may be effective for treating some, chronic conditions. Mechanism of Action / Pharmacology A) MECHANSIM OF ACTION 1) SUMMARY a) Clobetasol-17-propionate is a super-potent topical corticosteroid. It is a 21chloro-9-alpha-fluoro-corticosteroid, which derives its anti-inflammatory activity from the 11-beta-hydroxy group. This activity is enhanced by a fluorine atom in position 9 and a methyl group in position 16. 2) Corticosteroids have multiple mechanisms of action including anti-inflammatory activity, immunosuppressive properties, and antiproliferative actions [84] [85] . Anti-inflammatory effects result from decreased formation, release, and activity of the mediators of inflammation (eg, kinins, histamine, liposomal enzymes, prostaglandins, and leukotrienes). These effects reduce the initial manifestations of the inflammatory process [86] [87] [88] . Corticosteroids inhibit margination and subsequent cell migration to the area of injury, and also reverse the dilation and increased vessel permeability in the area, resulting in decreased access of cells to the sites of injury. This vasoconstrictive action decreases serum extravasation, swelling, and discomfort [86] . The immunosuppressive properties decrease the response to delayed and immediate hypersensitivity reactions (eg, type III and type IV) (Ricciatti & Lester, 1977). This results from inhibition of the toxic effect from antigen and antibody complexes that precipitate in vessel walls creating cutaneous allergic vasculitis, and by inhibiting the action of lymphokines, target cells, and macrophages which together produce allergic contact dermatitis reactions [86] . Additionally, the access of sensitized T lymphocytes and macrophages to target cells may also be prevented by corticosteroids [86] . The antiproliferative effects reduce hyperplastic tissue formation characteristic of psoriasis [89] [90] [91] . 3) The potency of topical corticosteroids is determined by the McKenzieStoughton vasoconstrictor assay [92] . The assay measures vasoconstriction, which is dependent on percutaneous absorption, caused by an agent. When this assay was developed in the 1960s, the correlation between vasoconstriction and clinical efficacy was considered to be good [93] [94] . However, clinical trials evaluating newer topical corticosteroids found differences between results of the vasoconstrictor assay and the therapeutic outcome of 11 out of 17 preparations. Additional clinical trials using a single disease and rigid criteria are needed to determine clinically relevant differences in efficacy, safety, and cost [95] . 4) Three-month treatment with clobetasol propionate 0.05% cream in 10 women with vulval lichen sclerosis et atrophicus modified the immunohistochemical parameters of skin immune system activation [96] . B) REVIEW ARTICLES 1) Guidelines regarding the use of topical corticosteroids, as well as suggestions for prevention of their misuse and toxicity, are available [97] . Therapeutic Uses Clobetasol Disorder of skin See Drug Consult reference: TOPICAL CORTICOSTEROIDS - DOSING GUIDELINES Clobetasol Propionate Chloasma a) Overview FDA Approval: Adult, no; Pediatric, no Efficacy: Adult, Evidence is inconclusive Recommendation: Adult, Class IIb Strength of Evidence: Adult, Category B See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Effective in one small study of patients with melasma (n=7) treated with clobetasol propionate [25] . c) Adult: 1) Seven patients with melasma showed 80% to 90% clearance of pigmentation after 6 to 8 weeks of treatment with clobetasol propionate 0.05% cream applied twice daily for 4 weeks followed by once daily for 4 weeks. Treatment was discontinued in 3 patients because of local atrophy and telangiectasia. In 4 patients, pigmentation reappeared 2 to 3 weeks after stopping treatment and returned to the pretreatment state in four to six months [25] . Disorder of skin See Drug Consult reference: TOPICAL CORTICOSTEROIDS - DOSING GUIDELINES Disorder of skin, Corticosteroid responsive FDA Labeled Indication a) Overview FDA Approval: Adult, yes (cream, emollient, foam, gel, lotion, ointment); Pediatric, yes (age 12 years or older (cream, emollient, foam, gel, ointment)) Efficacy: Adult, Effective; Pediatric, Effective Recommendation: Adult, Class IIb; Pediatric, Class IIb Strength of Evidence: Adult, Category B; Pediatric, Category B See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Clobetasol propionate is indicated for the short-term treatment (2 consecutive weeks or less) of inflammatory and pruritic corticosteroid-responsive dermatoses [1] [2] [3] [4] [5] [6] In a randomized study of 377 patients (12 years of age and older) with moderate to severe atopic dermatitis, 52% of patients treated with clobetasol propionate 0.05% foam topically twice daily for 2 weeks achieved treatment success compared with 14% of patients treated with vehicle foam [2] c) Adult: 1) In a randomized study of 377 patients (12 years of age and older) with moderate to severe atopic dermatitis, 52% (131 of 251) of patients treated with clobetasol propionate 0.05% foam topically twice daily for 2 weeks achieved treatment success compared with 14% (18 of 126) of patients treated with vehicle foam. The primary endpoint was treatment success, defined by an Investigator's Static Global Assessment (ISGA) score of clear (0) or almost clear (1) with at least 2 grades improvement from baseline, and scores of absent or minimal (0 or 1) for erythema and induration/papulation [2] . 2) Clobetasol is indicated for the short-term (2 weeks or less) treatment of inflammatory and pruritic corticosteroid-responsive dermatoses [1] [3] [4] [5] . Other uses include eczema [7] and psoriasis (when used alone or in combination with ultraviolet light) [8] [9] [10] [11] . Clobetasol has demonstrated similar or superior efficacy to other high-potency topical corticosteroids in treating psoriasis [12] [7] and has been effective in refractory disease [9] [13] . However, some investigators have found clobetasol's efficacy in psoriasis to be questionable [14] [15] [16] . 3) Therapy-resistant chronic atopic dermatitis completely resolved in 44 of 48 patients treated with clobetasol propionate lotion once a week under Duoderm(R) hydrocolloid dressing. Healing time ranged from 8 days to 2.5 weeks, and 2 patients developed a mild folliculitis [17] . 4) Two patients with inflammatory linear verrucous epidermal nevi (ILVEN) refractory to surgical excision or anthralin responded to topical 0.05% clobetasol propionate under occlusive dressing with or without salicylic acid [18] . Hemangioma a) Overview FDA Approval: Adult, no; Pediatric, no Efficacy: Pediatric, Evidence is inconclusive Recommendation: Pediatric, Class III Strength of Evidence: Pediatric, Category B See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Clobetasol treatment caused regression of capillary hemangiomas and associated visual defects in 3 infants [20] . c) Pediatric: 1) Clobetasol applied twice daily for 2 weeks with a 1-week drugfree interval produced regression of capillary hemangiomas on the eyelids of 3 infants under 6 months of age. All of the infants developed visual defects associated with enlargement of the tumor. Clobetasol therapy was repeated until the tumor regressed sufficiently to eliminate visual defects. In comparison to intralesional injection of corticosteroids, the tumors regressed more slowly, but the positive effect of clobetasol treatment continued after stopping the drug. None of the infants developed adrenal suppression [20] . Lichen sclerosus et atrophicus; Adjunct a) Overview FDA Approval: Adult, no; Pediatric, no Efficacy: Adult, Evidence favors efficacy Recommendation: Adult, Class IIb Strength of Evidence: Adult, Category B See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Use of clobetasol propionate 0.05% cream brought complete remission to 77% of 54 women with lichen sclerosus [22] . Topical clobetasol significantly reduced the symptom severity of penile lichen sclerosus et atrophicus (PLSA), in a retrospective study (n=21) [23] . Although clobetasol dipropionate 0.05% surpasses testosterone propionate 2% in treating signs and symptoms of lichen sclerosus, it still falls short of reliably curing this chronic cutaneous disorder of the vulva [24] . In another study, symptoms of vulval lichen sclerosus were alleviated in 13 patients treated with clobetasol propionate cream 0.05% for 12 weeks (Dalzial & Wojnarowska, 1993). c) Adult: 1) Topical clobetasol significantly reduced the symptom severity of penile lichen sclerosus et atrophicus (PLSA), in a retrospective study. Twenty-two men with histologically confirmed PLSA had received either topical clobetasol 0.05% cream as the initial treatment regimen (n=13), or clobetasol as a secondary treatment (n=9). Patients applied topical clobetasol 0.05% cream either once or twice daily, for an average treatment duration of 7 weeks. Significant reductions in the magnitude of most subjective symptoms (frequency/severity of itching and burning, soreness, erectile pain/discomfort, dyspareunia, urinary flow constriction and foreskin tightness) were reported, either directly after the last dose applied (p less than 0.001), or at long-term follow-up (p less than 0.01). Significant reductions were also observed in the histologic manifestations of PLSA (hyperorthokeratosis, dermal inflammation, epidermal atrophy and basal cell hydropic degeneration, p less than 0.05; dermal edema and collagen homogenization, p less than 0.01) within biopsy samples of the 15 patients deemed histologically evaluable. Nine patients were clinically free of PLSA at long-term follow-up, yet 41% of all patients treated continued to report persistence of diminished penile sensitivity after treatment [23] . 2) Although clobetasol dipropionate 0.05% surpasses testosterone propionate 2% in treating signs and symptoms of lichen sclerosus, unfortunately it still falls short of reliably curing this chronic cutaneous disorder of the vulva [24] . Over a period of six years 40 women with the disorder were given one of two instruction sets: to apply the testosterone ointment twice daily for 3 months, once daily for another 3 months, and finally two or three times a week; or to apply the clobetasol ointment twice daily for 1 month, once daily for another month, and finally one or two times a week. Short-term and long-term progress was noted at 3 months and 1 year, both subjectively by patients and objectively by one gynecologist. At the first follow-up examination women in both groups reported improvement, although objective signs differed significantly between groups in favor of the clobetasol treatment. Thereafter subjective and objective reports rated significantly more improvement in the clobetasol-treated group. Patients in the two groups stopped treatment for different reasons: Clobetasol-treated patients because of improvement of the condition; testosteronetreated patients for lack of response. It is also notable that side effects, mainly hyperandrogenism, occurred in 30% of women treated with testosterone. However, 8 of 18 patients successfully treated with clobetasol relapsed subjectively and objectively, and required intermittent repeat treatment with clobetasol. Regression analysis determined equivalency in baseline parameters between groups in this observational study, although instructions to the two groups differed in treatment interval, which raises compliance questions. 3) Use of clobetasol propionate 0.05% cream brought complete remission to 77% of 54 women with lichen sclerosus [22] . The women were recruited at one institution following a chart review of patients with symptomatic, biopsy-proven disease and treatments they had undertaken unsuccessfully; the average patient had tried 2.25 treatment modalities (range, 1 to 13). After enrollment, the treatment protocol was a standard regimen of clobetasol propionate 0.05% cream twice daily for one month, then at bedtime for one month, then twice a week for three months, and then as needed one or two times per week. At the 3-month evaluation, 76.8% of patients had complete remission of symptoms, 17.9% had partial remission, and 5.4% were unchanged. As to clinical appearance, 31.5% of patients had complete remission, 46.3% had partial remission, and 22% were unchanged. In 3 patients, burning and hyperemia secondary to contact dermatitis caused withdrawal from the study. Chi-square analysis of the women's prior treatments indicated a variety of symptomatic responses: Testosterone propionate 2% worked with erosions (p=0.056) and thinning (p=0.01); steroids worked on tearing (p=0.039) while petroleum jelly did not; and perineoplasty procedures were unsuccessful in both treating tissue bridges and erosions. 4) Symptoms of vulval lichen sclerosus were alleviated in 13 patients treated with clobetasol propionate cream 0.05% for 12 weeks. During a 39-month follow-up period, 4 women required further treatment periods of between 1 and 4 weeks. There was no evidence of steroid-induced atrophy, telangiectasia, striae, or secondary infection (Dalzial & Wojnarowska, 1993). Oral lichen planus a) Overview FDA Approval: Adult, no; Pediatric, no Efficacy: Adult, Evidence favors efficacy Recommendation: Adult, Class IIb Strength of Evidence: Adult, Category B See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Clobetasol was effective in the treatment of atrophic and erosive lesions of oral lichen planus [21] . Plasma cortisol levels were unaffected by long-term topical use of clobetasol c) Adult: 1) Clobetasol propionate 0.05% ointment was effective in controlling oral lichen planus, in a randomized, controlled, open- labeled clinical trial. Patients with histologically confirmed oral lichen planus were treated for 6 months with one the following regimens: fluocinonide 0.05% ointment with antimycotics applied 3 times daily for 2 months, twice-daily for 2 months, and once daily thereafter (n=24); clobetasol 0.05% ointment with antimycotics applied twice-daily for the first 4 months, and then once-daily thereafter (n=25); placebo plus antimycotics (n=11). All study drugs were formulated in a hydroxyethyl cellulose medium for oral adhesion. Every patient treated with clobetasol experienced some relief; 90% of patients treated with fluocinonide also experienced improvement. Clobetasol provided complete remission in 75% of patients compared with 25% of patients receiving fluocinonide and none receiving placebo (p=0.00442 and 0.00049, respectively). Clobetasol controlled symptoms significantly better than fluocinonide and placebo (p=0.00423 and 0.00041, respectively). Clobetasol was also more effective in treating atrophic lesions compared with fluocinonide (p=0.0044). Sixty-five percent of clobetasol patients were clinically stable at 6-month follow-up compared with 55% of fluocinonide patients. Oropharyngeal candidiasis was not observed; adverse events were otherwise limited to alterations in sense of taste and extrinsic staining of teeth, both attributed to concomitant use of antimycotic agents during the study [21] . Pemphigoid a) Overview FDA Approval: Adult, no; Pediatric, no Efficacy: Adult, Evidence is inconclusive Recommendation: Adult, Class IIb Strength of Evidence: Adult, Category B See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Topical clobetasol propionate promoted remission in 7 patients (3 with pemphigus vulgaris, 4 with pemphigus foliaceus), with healing of both cutaneous and mucosal lesions in an open-label, prospective study [29] . c) Adult: 1) Topical clobetasol propionate promoted clinical remission with healing of dermal and mucosal lesions in pemphigus bullous disease. In an open-label, prospective study, 7 patients (3 with PEMPHIGUS vulgaris, 4 with pemphigus foliaceus) were treated with clobetasol propionate 0.05% cream. All patients were classified as having mild disease severity, based upon the criteria of having fewer than 10 new bullous lesions per week and pemphigus antibody titer less than or equal to 1:320. Clobetasol propionate 0.05% cream was applied twice daily (average of 10 g/day) to all mucosal and skin lesions for a minimum of 15 days, followed by progressive dosage tapering, to an average of 5 g/day. Betamethasone valerate 0.1% cream was used for facial lesions, and 1 patient required pharyngeal application of beclomethasone spray. Healing of cutaneous lesions was observed within 15 days; mucosal lesion healing required a minimum of 1 month. Relapse was observed whenever dosage was reduced below 5 g/week, and was usually reversed with an increase in application frequency. Three patients with more severe relapses required administration of systemic treatment. There were no serious side effects reported [29] . Plaque psoriasis (Mild to Moderate) FDA Labeled Indication a) Overview FDA Approval: Adult, yes; Pediatric, yes (12 years or older (Olux(R) foam)) Efficacy: Adult, Evidence favors efficacy; Pediatric, Evidence favors efficacy Recommendation: Adult, Class IIb; Pediatric, Class IIb Strength of Evidence: Adult, Category B; Pediatric, Category B See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Clobetasol propionate is indicated in patients 12 years or older for the short-term (2 consecutive weeks or less) treatment of inflammatory and pruritic corticosteroid-responsive dermatoses [39] In a randomized study of 376 patients (12 years of age or older) with mild to moderate plaque-type psoriasis, 16% of patients treated with clobetasol propionate 0.05% foam topically twice daily for 2 weeks achieved treatment success compared with 4% of patients treated with vehicle foam [2] Clobetasol foam is effective for treatment of mild to moderate plaque-type psoriasis [35] Hyperproliferation-related keratin (K6) cell production in psoriasis was profoundly suppressed by the application of clobetasol-17propionate lotion under hydrocolloid occlusive dressing, in an openlabel, prospective study [36] A 0.05% emollient formulation of clobetasol produced notably less hypothalamic-pituitary-adrenal (HPA) axis suppression than the 0.05% cream formulation and was effective for use over a 4-week period in the treatment of psoriasis [38] c) Adult: 1) Foam a) In a randomized study of 376 patients (12 years of age and older) with mild to moderate plaque-type psoriasis, 16% (41 of 253) of patients treated with clobetasol propionate 0.05% foam topically twice daily for 2 weeks achieved treatment success compared with 4% (5/123) of patients treated with vehicle foam. The primary endpoint was treatment success, defined by an Investigator's Static Global Assessment (ISGA) score of clear (0) or almost clear (1) with at least 2 grades improvement from baseline, scores of none or faint/minimal (0 or 1) for erythema and scaling, and a score of none (0) for plaque thickness [2] . b) Topical clobetasol, delivered as foam, is effective for treatment of mild to moderate plaque-type psoriasis. Eighty-one patients with psoriasis on nonscalp sites were randomized in a ratio of 3 to 1 to receive clobetasol propionate foam or placebo foam. Components of foam were 0.05% clobetasol propionate (absent in placebo foam) in cetyl alcohol, stearyl alcohol, polysorbate 60, ethanol, purified water, propylene glycol, citric acid, anhydrous potassium citrate and a butane/propane propellant. Foam was applied twice daily for 2 weeks. In 2 weeks, 27% of clobetasol-treated patients showed marked or better improvement, compared to 5% of the placebo patients. The greater improvement was still evident 2 weeks after termination of treatment. Pruritus was eliminated in 50% of clobetasol-treated patients and in 20% of placebo- treated patients (p less than 0.02). The composite score of signs of psoriasis (erythema, scaling, plaque thickness) showed greater improvement with clobetasol than with placebo. Thirty percent of subjects in each group had adverse reactions that could have been related to the use of the foam [35] . 2) Emollient a) An emollient formulation of clobetasol produced notably less hypothalamic-pituitary-adrenal (HPA) axis suppression than the cream formulation, and was safe and effective for use over a 4week period in the treatment of psoriasis. This 2-phase safety/efficacy study compared clobetasol 0.05% emollient with 0.05% cream (1.5 g) in 12 patients with psoriasis or eczema during the safety phase. Only 1 patient in the emollient treatment group developed serum cortisol levels less than 10 mcg/100 mL, versus 4 in the cream treatment group. In the efficacy phase, 89 patients with moderate to severe plaque-type psoriasis (untreated for at least 2 weeks prior to study) received either clobetasol emollient (n=44) or emollient vehicle (n=45) on a double-blind, randomized, parallelgroup basis. Study treatments were applied 30 minutes after bathing to lesions anywhere on the body other than the face, scalp, axillae, groin, or rectal area. Treatment was continued twice daily for 4 weeks, not to exceed 50 g/wk. The emollient treatment group had significantly greater symptom and severity score improvement than the vehicle group, and only mild to moderate local adverse events. The emollient formulation of clobetasol may be clinically useful in dermatoses requiring more that a 2-week therapy duration [38] . 3) Ointment a) Clobetasol propionate 0.05% ointment applied twice daily for 2 weeks (less than 50 g/wk) promoted a dramatic reduction in symptoms of psoriasis and a progressive reduction in affected body surface area in 74 patients receiving up to 3 courses of treatment. A minimum interval of one week was required between courses. Nine patients (12%) had at least one abnormally low morning plasma cortisol level during therapy, and there was a strong correlation between percent body surface area treated and abnormal plasma cortisol levels [8] . b) In two small studies, clobetasol did not demonstrate therapeutic advantage over placebo in the treatment of psoriasis. Ninety patients were randomized to clobetasol, clobetasol with ultraviolet B (UVB) light, or placebo and UVB. There were 21 dropouts in this study. Among the remaining patients, combination clobetasol/UVB did not cause a significant decrease in healing time when compared with placebo/UVB, and single-agent clobetasol was less effective than either of the other treatment groups [15] . There was no statistical difference in efficacy between clobetasol 0.05% ointment applied for 2 weeks and clobetasol applied once daily for one week followed by placebo for one week in 12 psoriatic patients [14] . d) Pediatric: 1) Foam a) In a randomized study of 376 patients (12 years of age and older) with mild to moderate plaque-type psoriasis, 16% (41 of 253) of patients treated with clobetasol propionate 0.05% foam topically twice daily for 2 weeks achieved treatment success compared with 4% (5 of 123) of patients treated with vehicle foam. The primary endpoint was treatment success, defined by an Investigator's Static Global Assessment (ISGA) score of clear (0) or almost clear (1) with at least 2 grades improvement from baseline, scores of none or faint/minimal (0 or 1) for erythema and scaling, and a score of none (0) for plaque thickness [2] . Plaque psoriasis (Moderate to Severe) FDA Labeled Indication a) Overview FDA Approval: Adult, yes (cream, emollient, lotion, spray); Pediatric, yes ( 16 years or older (Embeline(R) E emollient, Temovate(R)-E cream, emollient); 18 years or older (Clobex(R) lotion, spray)) Efficacy: Adult, Evidence favors efficacy; Pediatric, Evidence favors efficacy Recommendation: Adult, Class IIb; Pediatric, Class IIb Strength of Evidence: Adult, Category B; Pediatric, Category B See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Temovate(R) E cream and Embeline(R) E emollient are indicated in patients 16 years or older for treatment for up to 4 consecutive weeks of moderate to severe plaque-type psoriasis [1] . Clobex(R) spray and lotion are indicated for the treatment of adults with moderate to severe plaque psoriasis [32] [6] . In a randomized study of 376 patients (12 years of age or older) with mild to moderate plaque-type psoriasis, 16% of patients treated with clobetasol propionate 0.05% foam topically twice daily for 2 weeks achieved treatment success compared with 4% of patients treated with vehicle foam [2] . Clobetasol foam is effective for treatment of mild to moderate plaque-type psoriasis [35] . Hyperproliferation-related keratin (K6) cell production in psoriasis was suppressed by the application of clobetasol-17-propionate lotion under hydrocolloid occlusive dressing, in an open-label, prospective study [36] . A combination of 2 weeks of clobetasol propionate to promote rapid healing, followed by 4 weeks of a nonsteroidal antipsoriatic treatment for maintenance, has been shown to restore barrier function of the skin in severe plaque psoriasis [37] . A 0.05% emollient formulation of clobetasol produced less hypothalamic-pituitary-adrenal (HPA) axis suppression than the 0.05% cream formulation and was effective for use over a 4-week period in the treatment of psoriasis [38] . c) Adult: 1) Emollient a) An emollient formulation of clobetasol produced less hypothalamic-pituitary-adrenal (HPA) axis suppression than the cream formulation, and it was safe and effective for use over a 4week period in the treatment of psoriasis. This 2-phase safety and efficacy study compared clobetasol 0.05% emollient with 0.05% cream (1.5 g) in 12 patients with psoriasis or eczema during the safety phase. Only 1 patient in the emollient treatment group developed serum cortisol levels less than 10 mcg/100 mL, versus 4 in the cream treatment group. In the efficacy phase, 89 patients with moderate to severe plaque-type psoriasis (untreated for at least 2 weeks prior to study) received either clobetasol emollient (n=44) or emollient vehicle (n=45) on a double-blind, randomized, parallelgroup basis. Study treatments were applied 30 minutes after bathing to lesions anywhere on the body other than the face, scalp, axillae, groin, or rectal area. Treatment was continued twice daily for 4 weeks, not to exceed 50 g/wk. The emollient treatment group had significantly greater symptom and severity score improvement than the vehicle group and only mild to moderate local adverse events. The emollient formulation of clobetasol may be clinically useful in dermatoses requiring more that a 2-week therapy duration [38] . 2) Lotion a) Hyperproliferation-related keratin (K6) cell production in psoriasis was suppressed by the application of clobetasol-17-propionate lotion under hydrocolloid occlusive dressing, in an open-label, prospective study. Seven patients with clinically stable psoriasis received hydrocolloid-occlusive treatment of moderately severe psoriatic plaques (minimum SUM score of 6 from the Psoriasis Area and Severity Index) with clobetasol lotion (concentration unspecified). Each target lesion was treated weekly for up to 6 weeks or until clearance. Lesion biopsies and flow cytometry were performed before treatment, after clearance, and at apparent relapse. All patients achieved clearance within 6 weeks. Postclearance biopsy demonstrated a significant reduction in proportion of proliferative K6-positive keratin cells (p less than 0.05), while the proportion of K10-positive cells returned to within normal range (p less than 0.01). Subsequent follow-up confirmed the recurrence of plaque formation; however, the associated SUM severity scores revealed only one-half the severity (SUM=3) of pretreatment lesions, leading the authors to propose the phenomenon of rebound versus relapse after the withdrawal of potent corticosteroid treatment. Such a rebound phenomenon would support the establishment of a maintenance therapy regimen to maintain the suppression of keratin cell hyperproliferation [36] . 3) Ointment a) A combination of 2 weeks of clobetasol propionate to promote rapid healing, followed by 4 weeks of a nonsteroidal antipsoriatic treatment for maintenance, has been shown to restore barrier function of the skin in severe plaque psoriasis . In this randomized, double-blind comparison, patients applied clobetasol propionate (0.05%) ointment to one side of the body for 2 weeks and then calcipotriol (50 mcg/g) ointment for 4 weeks; on the other side of the body, patients applied calcipotriol (50 mcg/g) ointment alone for 6 weeks. At the end of active treatment, lesions that had received the combination had significantly lower overall severity scores than lesions receiving the vitamin D(3) analogue calcipotriol only (p=0.0002). No rebound effect occurred after termination of treatment, although lesions gradually recurred after either treatment [37] . b) Clobetasol propionate 0.05% ointment applied twice daily for 2 weeks (less than 50 g/wk) promoted a reduction in symptoms of psoriasis and a progressive reduction in affected body surface area in 74 patients receiving up to 3 courses of treatment. A minimum interval of 1 week was required between courses. Nine patients (12%) had at least 1 abnormally low morning plasma cortisol level during therapy, and there was a strong correlation between percent body surface area treated and abnormal plasma cortisol levels [8] . c) In two small studies, clobetasol did not demonstrate therapeutic advantage over placebo in the treatment of psoriasis. Ninety patients were randomized to clobetasol, clobetasol with ultraviolet B (UVB) light, or placebo and UVB. There were 21 dropouts in this study. Among the remaining patients, combination clobetasol/UVB did not cause a significant decrease in healing time when compared with placebo/UVB, and single-agent clobetasol was less effective than either of the other treatment groups [15] . There was no statistical difference in efficacy between clobetasol 0.05% ointment applied for 2 weeks and clobetasol applied once daily for one week followed by placebo for one week in 12 psoriatic patients [14] . 4) Spray a) Moderate or severe psoriasis improved with clobetasol topical spray 0.05% compared with vehicle control in 2 randomized trials. Patients with moderate or severe/very severe plaque psoriasis received either topical clobetasol propionate 0.05% spray or vehicle spray for 4 weeks. Based on Overall Disease Severity (5-point scale based on scaling, erythema, and plaque elevation), clobetasol was superior to the vehicle control: [32] .

In both trials, patients were treated with clobetasol propionate shampoo 0.05% or a corresponding vehicle once daily for 15 minutes over a period of 4 weeks. Success rates, defined as the proportion of patients with a 0 (clear) or 1 (minimal) on a 0 to 5 point physician's Global Severity Scale for scalp psoriasis, were 42% and 28% in the groups using clobetasol compared to 2% and 10% in the groups using shampoo vehicle. The percentage of patients with 0 (clear) on a 0 to 3-point scalp psoriasis parameter scale for parameters of erythema, scaling, and plaque thickening at the end of both studies were: PARAMETER Erythema Scaling Plaque Thickening CLOBETASOL SHAMPOO 18% and 12% 22% and 15% 37% and 34% PLACEBO 6% and 2% 0% and 4% 11% and 10% The study did not have a sufficient number of non-Caucasian patients to determine whether they respond differently than Caucasian patients with regard to safety and efficacy [44] . Tight foreskin a) Overview FDA Approval: Adult, no; Pediatric, no Efficacy: Pediatric, Evidence is inconclusive Recommendation: Pediatric, Class IIb Strength of Evidence: Pediatric, Category B See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Unretractable foreskin (phimosis) was successfully treated in 9 of 15 pediatric patients using topical clobetasol 0.5% once daily for 4 weeks, with frequent manual retraction after the first week of therapy [30] . Clobetasol cream was successful in 38 of 54 boys (ages 2 to 15 years) with phimosis. Up to 90% of surgically treated cases of phimosis have been caused by lichen sclerosus, a condition that has been treated with clobetasol propionate cream [31] . c) Pediatric: 1) Unretractable foreskin (phimosis) was successfully treated in 9 of 15 pediatric patients using topical clobetasol 0.5% once daily for 4 weeks with frequent manual retraction after the first week of therapy. One patient required 2 months of clobetasol treatment before phimosis disappeared. Another patient's phimosis resolved only after a total of 14 weeks, but this patient's therapy compliance was questionable. Among 15 placebo-treated patients, 5 had resolution of phimosis; 7 were crossed over to clobetasol for 6 weeks with complete resolution. Overall, clobetasol ointment was effective in 18 of the 20 patients (90%) who used it for a median of 6 weeks during active or crossover phases of the trial [30] . 2) Clobetasol cream was successful in 38 of 54 boys (ages 2 to 15 years) with phimosis. Up to 90% of surgically treated cases of phimosis have been caused by lichen sclerosus, a condition that has been treated with clobetasol propionate cream. Clobetasol was applied once daily to the outside of the prepuce for a mean of 49 days. No skin atrophy or other side effects were reported. Patients not cured after 3 months of treatment were referred to surgery [31] . Urticaria pigmentosa a) Overview FDA Approval: Adult, no; Pediatric, no Efficacy: Adult, Evidence is inconclusive Recommendation: Adult, Class IIb Strength of Evidence: Adult, Category C See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Clobetasol propionate was successful in one case report of adultonset urticaria pigmentosa [40] . c) Adult: 1) Adult-onset urticaria pigmentosa cleared following application of clobetasol propionate 0.05% daily for 4 weeks . The patient previously had an excellent response to psoralen plus ultraviolet A, but the eruption recurred immediately after stopping therapy. The patient maintained remission by using a single once-monthly application of clobetasol ointment [40] . Vesicular stomatitis a) Overview FDA Approval: Adult, no; Pediatric, no Efficacy: Adult, Evidence favors efficacy Recommendation: Adult, Class IIb Strength of Evidence: Adult, Category B See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Clobetasol propionate mouthwash (0.05%) was an effective treatment for severe, erosive lesions of the oral mucosa in an uncontrolled study (n=30) [26] . Clobetasol propionate was comparable to fluocinonide in an adhesive paste in a double-blind study of 60 patients with lichen planus, pemphigus, or erythema multiforme [27] . c) Adult: 1) Clobetasol propionate mouthwash (0.05%) was an effective treatment for severe, erosive lesions of the oral mucosa. In an uncontrolled study, 30 patients were given 10 mL of an aqueous solution containing 0.05% clobetasol propionate and nystatin 100,000 international units/mL, which they were to swish in their mouth for 5 minutes and not swallow. Treatments were 3 times daily for 48 weeks. Pain ulceration disappeared in 93% of cases, with 90% reporting resumption of daily activities. Two patients had no response to therapy and 5 patients suffered adverse effects (moon face and hirsutism), which responded to a reduction in the frequency of mouthwash [26] . 2) Clobetasol was similar in efficacy to fluocinonide mixed with an adhesive paste (Orabase(R)) in relieving the symptoms and ulcers associated with oral vesiculoerosive disease (OVED) in a doubleblind study comprising 60 patients with lichen planus, pemphigus, or erythema multiforme. Although not statistically significant, clobetasol-treated patients had earlier improvement in symptoms and pain than those treated with fluocinonide. There were no significant differences between treatments for development of hypothalamic-pituitary-adrenal axis suppression or clinical candidiasis [27] . 3) Twenty-two of 24 patients with chronic oral vesiculoerosive disease (OVED) responded to treatment with clobetasol propionate 0.05% ointment in an adhesive paste (Orabase(R)), applied to lesions 2 to 3 times daily for 2 to 4 weeks. Fifteen patients had complete remission and 7 had excellent or good responses. Responding patients remained disease-free with continued use of clobetasol for up to 6 months [28] . Vitiligo a) Overview FDA Approval: Adult, no; Pediatric, no Efficacy: Adult, Evidence is inconclusive Recommendation: Adult, Class IIb Strength of Evidence: Adult, Category B See Drug Consult reference: RECOMMENDATION AND EVIDENCE RATINGS b) Summary: Clobetasol has been used in this condition, but side effects limit applicability Repigmentation varied from 15% to 90% c) Adult: 1) Over a period of 8 months or less, 88% of 25 patients with vitiligo had at least 90% repigmentation after treatment with clobetasol cream (applied twice daily; maximum 12 g every 2 weeks) . However, side effects were frequent (acne, skin atrophy, telangiectasia, fungal infections) [41] . 2) Successful repigmentation was achieved in more than 80% of patients treated with clobetasol 0.05% in 50% isopropanol for vitiligo of the trunk and limbs, and in more than 40% of patients receiving clobetasol as an ointment to the face and eyelids. Patients (n=75) used the medication twice daily for 2 months on the face and 4 months elsewhere [42] . 3) Segmental vitiligo, an entity with a unilateral distribution distinct from that of the nonsegmental variety, showed promising results of topical treatment with clobetasol propionate 0.05% cream in a small study . Out of 38 evaluated patients, 13 (34.2%) evidenced more than 50% repigmentation of vitiliginous areas, with best results seen in facial areas. Time before treatment was a significant factor in response, with repigmentation occurring in significantly more patients treated within 12 months of onset than in patients treated more than 1 year after symptoms began (p less than 0.05). The cream was applied to vitiliginous areas twice daily in patients with a definite diagnosis of segmental vitiligo and disease durations ranging from 1 month to 12 years. Unless severe side effects required otherwise, every 6 weeks of therapy was followed by 2 weeks of rest, and responding patients received 3 courses. Side effects required longer treatment interruptions of up to 4 weeks in 10 patients; 6 patients had mild atrophy, 4 telangiectasia, and 8 acneiform papules (Khalid & Mujtaba, 1998). Comparative Efficacy / Evaluation With Other Therapies Amcinonide 1) Efficacy a) The following groups of topical corticosteroids indicate comparative potencies [101] : Relative Potencies of Commonly Used Topical Corticosteroids (Group 1, Most Potent; Group 6, Least Potent) 1. Clobetasol propionate 0.05% 2. Amcinonide 0.1% Betamethasone dipropionate 0.05% Desoximetasone 0.25% Diflorasone diacetate 0.05% Fluocinonide 0.05% Halcinonide 0.1% 3. Betamethasone valerate 0.1% Fluocinolone acetonide 0.025% Flurandrenolide 0.05% Triamcinolone acetonide 0.5% 4. Fluocinolone acetonide 0.025% Hydrocortisone valerate 0.2% Triamcinolone acetonide 0.1% 5. Desonide 0.05% Flumethasone pivalate 0.03% Hydrocortisone 1% (with urea) 6. Dexamethasone 0.1% Hydrocortisone 1% (alcohol or acetate) Anthralin Plaque psoriasis a) A small, open trial in 10 in-patients with plaque psoriasis compared the efficacy of clobetasol 0.05% ointment with anthralin 0.25% in zinc and salicylic acid paste (Lassar's paste), applied twice daily to the right and left side of the body, respectively. Plaque clearing occurred between 10 and 21 days. Length of remission was significantly longer with clobetasol therapy versus anthralin (p less than 0.005). Both therapies resulted in satisfactory plaque clearance over a comparable time frame. Clobetasol had the added benefit of not causing the skin irritation and staining associated with anthralin [128] . b) An open, randomized trial compared the effects of anthralin and UVB irradiation (Ingram regimen) with and without the addition of clobetasol ointment in 50 out-patients with plaque psoriasis. After treatment with UVB irradiation, all patients received anthralin 0.05% to 2% daily for 4 hours until plaques cleared, then twice weekly for 4 weeks. Twenty-six patients also received a tapering regimen of clobetasol for 4 weeks. The median time for plaque clearance was 2.5 weeks with anthralin and clobetasol therapy, versus 4 weeks with anthralin alone (p less than 0.05). Overall response rates and adverse events were comparable between treatment groups. Although relapse tended to occur more frequently in the clobetasoltreated patients, the rate between the two treatment groups was not significant [129] . Betamethasone Psoriasis a) Summary: In most studies, clobetasol was more effective than betamethasone in the treatment of psoriasis vulgaris. It appears that the base (cream, ointment, or alcoholic solution) affects absorption as well as efficacy. b) Clobetasol propionate was shown to be more effective than betamethasone valerate, a mid-potency corticosteroid cream [121] , ointment (Corbett, 1976), and lotion [122] formulations when compared in controlled studies with like formulations. c) Alcoholic solutions of clobetasol and betamethasone dipropionate were compared in patients with scalp psoriasis. Both treatment groups showed a decrease in scaling and itching of lesions. Complete induration of lesions occurred in 80% of the patients receiving clobetasol compared with 55% in the betamethasone group [123] . d) In a series of studies, clobetasol propionate ointment was compared to betamethasone dipropionate in an optimized ointment (super high potency) [124] [125] . Both treatments were equi-effective but in another trial significantly more crobetasol propionate patients had a better response than the betamethasone group [126] . Calcipotriene Psoriasis a) Calcipotriene (CPT) ointment twice daily in combination with tazarotene (TZT) gel once daily was as effective as clobetasol (CBS) ointment used twice daily in the treatment of plaque psoriasis. In a prospective, open-label, right/left comparison, pilot study, patients (n=15) with at least 1 "mirror-image" pair of symmetric lesions of plaque psoriasis and an established diagnosis of psoriasis vulgaris, which was clinically stable for the previous month, received therapy for two weeks, then underwent observation during a 4-week post-treatment period. Following a washout phase, 28 target lesion pairs were randomly assigned to treatment in which one lesion received two weeks of therapy with CPT ointment and TZT gel each morning plus CPT ointment in the evening and the matched lesion received CBS ointment twice daily for two weeks. Erythema, scaling, plaque elevation and overall lesional severity were assessed at 0, 2, 4, and 6 weeks. At 2 weeks, lesions treated with CPT plus tazarotene showed almost equal reductions in scaling, plaque elevation, and overall lesional severity as compared with the CBS-treated lesions. During the 2-week treatment phase, erythema was significantly more improved in lesions treated with clobetasol (p less than 0.01) than with the combination therapy. During the observation phase, plaque elevation reappeared more quickly in the CPT-plus-TZT-treated lesions (p less than 0.01) than in the CBS- treated lesions. However, no difference was seen in changes in scaling, erythema, and overall lesional severity between the two therapies. Both treatments were well tolerated. No adverse events were reported in the CBS group. Adverse events in the CPTplus-TZT group were mild, including asymptomatic erythema and peeling [127] . Cyclosporine Psoriasis a) The addition of clobetasol to cyclosporine A cleared psoriasis faster than cyclosporine A alone but did not slow the relapse rate [118] . Diflorasone Psoriasis a) Diflorasone diacetate 0.05% in a potency-enhancing ointment vehicle (Psorcon(R)) was compared to clobetasol propionate 0.05% ointment in 60 patients with moderate to severe psoriasis using a bilateral, paired-comparison double-blind design [130] . Patients were treated twice a day for two weeks. There was a two week follow-up period. Results indicate a more rapid clearing with clobetasol propionate. Clobetasol was significantly more effective in reducing erythema, scaling and skin thickening at the one-week, two-week and follow-up evaluations. The clobetasol treated lesions displayed clearing in 21% of the patients at the two-week evaluation, compared to 9% with diflorasone diacetate (p less than 0.05). Diflucortolone Eczema a) Two studies comparing the topical effectiveness of clobetasol propionate 0.05% and diflucortolone valerate 0.3% cream reported comparable effectiveness with no significant differences between them. Incidence and severity of side effects were also similar [119] [120] . Fluocinolone Psoriasis a) In a multi-comparative study involving 1150 patients with psoriasis or eczema, clobetasol 0.05% for seven days was found to be more effective in improving the conditions than betamethasone, fluocinolone, or fluclorolone [110] . b) In a double-blind comparison study of twice-daily 0.05% clobetasol ointment versus 0.025% fluocinolane acetonide ointment, it was found that resolution lasted longer and relapses were less severe on the sides treated with clobetasol ointment [111] . Fluocinonide Disorder of oral soft tissues a) Clobetasol propionate 0.05% and fluocinonide 0.05% mixed in Orabase produced similar decreases in erythema, atrophy, and ulcer size in patients with oral vesiculoerosive disease [112] . Seventy-five percent of the observations in each group showed improvement. There were not significant differences between treatments; however, pain control was better in the clobetasol group during the first and second weeks. This study included 60 patients with lichen planus (n=35), benign pemphigoid (n=3), pemphigus vulgaris (n=3), and erythema multiforme (n=19). This was a randomized, double-blind clinical trial which lasted 28 days (eg, 2 weeks on treatment, 2 weeks off treatment). Psoriasis a) SUMMARY: Clobetasol appears to be superior to fluocinonide in the treatment of psoriasis and eczema. Clobetasol should be used only for short courses (2 weeks maximum) and assessment of hypothalamic-pituitary-adrenal axis (HPA) function is required if longer therapy is administered [113] . b) Clobetasol propionate cream (0.05%) was significantly more effective than fluocinonide cream (0.05%), each applied three times daily for 2 weeks, in the treatment of moderate-to-severe psoriasis and eczema in a multicenter double-blind study involving 227 patients [114] . Clobetasol was associated with greater resolution of signs and symptoms and more rapid healing of lesions; fewer relapses occurred after clobetasol therapy. Fluocinonide was associated with a greater incidence of side effects (12% versus 4%). Morning cortisol levels were below 5 mcg/dL in 6% of clobetasol-treated patients compared to one fluocinonide-treated patient after 2 weeks of treatment. This suggests a greater propensity of clobetasol to induce adrenal suppression. c) Clobetasol propionate ointment 0.05% applied once daily was superior to fluocinonide 0.05% ointment applied three times daily in the treatment of moderate-to-severe psoriasis in a 2-week singleblind study involving 125 patients [115] . At the end of two weeks of treatment, marked improvement or clearing of lesions was observed in 61% of clobetasol-treated patients and in 38% of fluocinonide-treated patients. At seven days post-treatment (day 22), marked improvement or clearing of lesions was observed in 42% and 23% of clobetasol- and fluocinonidetreated patients, respectively. While the morning plasma cortisol levels dropped below 5 mcg% in two patients (3%) receiving clobetasol, levels returned to normal within one week following therapy. Halcinonide Psoriasis a) Although one early study found no statistically significant difference between paired psoriatic lesions treated with either the class II 0.1% halcinonide cream or clobetasol cream [105] , a more recent study employing a larger patient population found clobetasol to be superior [106] . In this later double-blind comparison study of 70 patients with psoriasis, 42.9% of the clobetasol-treated sides had greater than 75% clearing versus only 15.8% of the halcinonide-treated sides. Of sixty-two follow-up patients examined two weeks after treatment, 62.9% relapsed first on the halcinonide-treated side versus 3.2% on the clobetasol-treated side. Halobetasol Atopic dermatitis a) Halobetasol ointment or clobetasol was given 127 patients with chronic, localized atopic dermatitis or lichen simplex chronicus in a multicenter, parallel-group comparative trial [108] . The success rates of healed or marked improvement were similar for the treatments (93.7 vs 92.2%, respectively). Healing was reported in a higher proportion of patients treated with halobetasol (65.1% and 54.7%). Both preparations were well tolerated. b) In a double-blind, parallel-group study, halobetasol and clobetasol cream were compared in patients with acute, severe exacerbations of atopic dermatitis [109] . All patients had satisfactory and similar results. Psoriasis a) A double-blind, parallel-group study comparing 0.05% halobetasol ointment and 0.05% clobetasol ointment was reported in 134 patients with psoriasis [107] . A significantly larger proportion of patients treated with halobetasol had no or mild disease after 14 days compared with those treated with clobetasol (86% vs 70%). Adverse events were reported in a smaller percentage of patients treated with halobetasol (7% vs 12%, respectively). Hydrocortisone Eczema a) Clobetasol was of comparable efficacy to hydrocortisone in 40 patients with symmetrical eczematous lesions. A double-blind trial was conducted using clobetasol 0.05% and hydrocortisone 0.1% in cream bases. Seven cases showed a favorable response to clobetasol and nine cases to hydrocortisone. In 24 cases both sides responded equally. Complete healing after two weeks' treatment occurred in eight cases with clobetasol and 10 hydrocortisonetreated cases [116] . Psoriasis a) Five different corticosteroid lotions occluded under a hydrocolloid dressing (Actiderm) for one week in patients with psoriasis (n=23), eczema (n=8), and other dermatoses (n=9) were observed [117] . Preparations applied included clobetasol propionate 0.05%, betamethasone valerate hydrocortisone 1% dissolved in 99% alcohol, and an alcohol control. Medication was re-applied under the hydrocolloid dressing for a second week. Areas treated with clobetasol, betamethasone, and triamcinolone were clinically healed in four patients in one week, with residual redness in four others. Patients treated only with betamethasone valerate under hydrocolloid dressing once a week for three weeks also had healed lesions for various dermatoses. Results showed no advantage of using the more potent corticosteroid, clobetasol, under the hydrocolloid dressing. Hydrocortisone did not induce healing as well as did other corticosteroids. Adverse Effects a) A long-term double-blind study attempted to assess side effects in 10 volunteers who received six different ointments (hydrocortisone 1%/urea 10%, hydrocortisone butyrate 0.1%, clobetasol propionate 0.05%, clobetasol butyrate 0.05%, urea 10%, and white soft paraffin) applied to six different sites on the forearm (Dykes & Markes, 1977). Over the eight weeks of therapy, all sites showed some atrophy. Only clobetasol propionate showed a statistically significant difference between initial and final skin thickness. Pimecrolimus Psoriasis a) In one small randomized comparison with topical clobetasol (nonblinded), pimecrolimus 1% ointment applied once daily for 2 weeks under Finn chamber occlusion significantly reduced clinical scores compared to placebo (82% versus 18%). With clobetasol 0.05% ointment under occlusion, efficacy was statistically similar (92% decrease in scores) [104] . Tazarotene Psoriasis a) Calcipotriene (CPT) ointment twice daily in combination with tazarotene (TZT) gel once daily was as effective as clobetasol (CBS) ointment used twice daily in the treatment of plaque psoriasis. In a prospective, open-label, right/left comparison, pilot study, patients (n=15) with at least 1 "mirror-image" pair of symmetric lesions of plaque psoriasis and an established diagnosis of psoriasis vulgaris, which was clinically stable for the previous month, received therapy for two weeks, then underwent observation during a 4-week post-treatment period. Following a washout phase, 28 target lesion pairs were randomly assigned to treatment in which one lesion received two weeks of therapy with CPT ointment and TZT gel each morning plus CPT ointment in the evening and the matched lesion received CBS ointment twice daily for two weeks. Erythema, scaling, plaque elevation and overall lesional severity were assessed at 0, 2, 4, and 6 weeks. At 2 weeks, lesions treated with CPT plus tazarotene showed almost equal reductions in scaling, plaque elevation, and overall lesional severity as compared with the CBS-treated lesions. During the 2-week treatment phase, erythema was significantly more improved in lesions treated with clobetasol (p less than 0.01) than with the combination therapy. During the observation phase, plaque elevation reappeared more quickly in the CPT-plus-TZT-treated lesions (p less than 0.01) than in the CBS- treated lesions. However, no difference was seen in changes in scaling, erythema, and overall lesional severity between the two therapies. Both treatments were well tolerated. No adverse events were reported in the CBS group. Adverse events in the CPTplus-TZT group were mild, including asymptomatic erythema and peeling [103] . REFERENCES 1.
