To soothe and relieve minor skin irritations, including pain, insect bites, rashes and discomfort, particularly brought on by poison ivy, poison oak and poison sumac. A skin protectant for first degree and minor second-degree thermal burns and sunburns. Sources of information: electronic Medicines Compendium Martindale Micromedex Pray W. Non-prescription Drug Therapeutics, Lippincott Williams and Wilkins Product label U.S. Food and Drug Administration (FDA) Therapeutic Classification: Astringent Skin protectant 10 Topical antipruritic/antihistamine Mechanism of Action(s): Calamine acts as an astringent by coagulating protein to constrict skin tissues and blood capillaries as well as decrease cell volume, thus minimising oozing, discharge or bleeding when applied to the skin. A powdery zinc oxide layer is left on the skin upon application; hence it acts as a skin protectant in addition to calamine. As an antihistamine, calamine helps to relieve itching and swelling caused by the release of histamines during the body’s exposure to allergens. It also has absorbant properties, helping to absorb fluids from weeping lesions of poison ivy/oak/sumac dermatitis. Sources of information: Martindale Micromedex MIMS Pray W.

It relieves pain indirectly by stimulating rather than suppressing sensations of warmth, and sometimes itching. It also has nasal decongestant activity which is able to relief cold and flu symptoms if inhaled. It loosens congestion in the chest and releases mucous build up. Source of information: APhA Handbook of Non-prescription Drugs, WHO Monographs on Selected Medicinal Plants (Volume 2) 13 Available Dosage Form(s): - Essential oil - Liniment - Lotion - Ointment - Tincture Source of information: AltMedDex® Dosing and Administration: For Adults and Children > 2 years: - Topical: For use as a topical rubefacient, apply 0.5% to 3% concentration to the affected area not more than three or four times a day. For common cold and coughs, oil can be applied and massaged briskly onto the chest and back. For use to alleviate body chills, the oil can be rubbed onto the chest and back gently to increase body warm. For joint and muscular aches, sprains, and bruises, the oil should be gently massaged onto the affected parts until a warm glow is felt. It is then repeated at intervals until the pain or swelling disappears. - Inhalation: For inhalation, add 12 drops of eucalyptus oil to a bowl of 150ml of boiling water, cover the head with a towel and inhale the penetrating vapours to help relief cold and flu symptoms. To clear nasal passages, sprinkle a few drops on tissue or handkerchief and inhale gently.

Treatment of serborrhoeic dermatitis, a skin condition related with the presence of Pityrosporum ovale and pityriasis capititis (dandruff on the scalp) due to fungal infection in adults. 37 Also used in the treatment of cutaneous candidosis and tinea/pityriasis versicolor (white spots). Source of information: British National Formulary (BNF) MIMS Product information of Nizoral Cream Therapeutic Classification: Topical Antifungals Mechanism of Action(s): Has a potent antifungal activity against dermatophytes eg, Trichophyton species, Epidermophyton floccosum and Microsporum species. Also useful against yeasts including Malassezia species. Ketoconazole is structurally similar to imidazole which interferes with the fungal synthesis of ergosterol, a constituent of cell membranes, as well as certain enzymes. It interacts with 14-α demethylase, a cytochrome P-450 enzyme necessary for the conversion of lanosterol to ergosterol. This results in inhibition of ergosterol synthesis and increased fungal cellular permeability – ultimately preventing the growth of the fungi. Ketoconazole is specific for fungi and not other microorganisms. Other mechanisms may involve the inhibition of endogenous respiration, interaction with membrane phospholipids, inhibition of yeast transformation to mycelial forms, inhibition of purine uptake, and impairment of triglyceride and/or phospholipid biosynthesis. Ketoconazole can also inhibit the synthesis of thromboxane and sterols such as aldosterone, cortisol, and testosterone.

Source of information 1. Martindale: The Complete Drug Reference. Sean C. Sweetman. Pharmaceutical Press, 2009. 36th Edition.Volume 1. London; Chicago. Dosing and Administration: Amorolfine nail lacquer contains an equivalent of 5% amorolfine and is applied to affected fingernails or toenails once or twice weekly. Administration should be practiced as follows: Before painting amorolfine nail lacquer, the infected areas of the nail have to be filed down as thoroughly as possible and the surface cleansed with a cleaning pad. A spatula with a measured dosage is supplied. Using this spatula, dip it into the lacquer and avoid wiping it on the neck of the bottle before applying it on the affected area of the nail. Allow the nail to dry as the solvent evaporates to leave a highly concentrated deposit of amorolfine in an occlusive film on the nail. It acts as a depot from which amorolfine penetrates and diffuses through the nail plate into the nail bed. Treatment should be continued until the infected nails are completely cured and regrown. This will normally take 6 months for fingernails and 9 to 12 months for toenails. 56 Source of information 1. Martindale: The Complete Drug Reference. Sean C. Sweetman.

Injection: - - - - Use the syringe marked for the strength of insulin to be injected as failure to do so can lead to mistake in dosage. Ensure patient is aware of proper injecting technique and care must be taken to ensure that the injection does not enter the blood vessel. Prepare patients for possible bruising due to improper injection techniques. Remind patient to be consistent with the area of the body that is injected. (Eg, buttocks, abdomen, thighs or upper arms. However, patient should rotate the injections between various sites within the same area. Do not use Humulin if insulin substance remains at the bottom of the bottle after mixing. Do not use if there are clumps in the insulin after mixing and if solid particles stick to the bottom or wall of the bottle, giving it a frosted appearance. 61 Lifestyle: Patient ability to concentrate and react may be impaired as a result of hypoglycaemia and should be advised to avoid driving and operating heavy machinery when hypoglycemic. Patient should be counselled on using glucometers to monitor their blood glucose level regularly. In particular, expectant mothers should monitor their blood glucose to meet the changing needs for insulin during and after pregnancy to prevent maternal and fetal problems.

Source(s) of information: http://www.rxlist.com http://www.medicinenet.com http://www.mims.com.sg Legal Classification in Singapore: Pharmacy Only Source of information: http://www.hsa.gov.sg Approved Indication(s): Salbutamol syr/tab belongs to the class of antiasthmatic and COPD preparations, and is used for the relief of bronchospasm in chronic bronchitis, emphysema and bronchial asthma. Salbutamol tab is also used for maintenance therapy in premature labour. Source of information: http://www.mims.com.sg Therapeutic Classification: Beta-adrenergic Agonist Mechanism of Action(s): The racemic form of albuterol, albuterol sulphate, is a relatively selective beta2adrenergic bronchodilator. 92 Albuterol’s primary action is to stimulate adenyl cyclase which catalyzes the formation of cyclic AMP from ATP in beta-adrenergic cells. Increased cyclic AMP levels lead to relaxation of bronchial smooth muscles and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells. Albuterol is rapidly and well absorbed following oral administration. After oral administration of 10 mL of Salbutamol Syrup (4 mg albuterol) in normal volunteers, maximum plasma albuterol concentrations of about 18 ng/mL are achieved within 2 hours, and the drug is eliminated with a half-life of about 5 to 6 hours. Source(s) of information: http://www.hc-sc.gc.ca http://www.rxlist.com Available Dosage Form(s): Salbutamol syrup (Ventolin) contains 2mg of albuterol as 2.4mg of albuterol sulphate in each 5ml of the syrup. It is a clear yellow liquid and artificially flavoured with strawberry flavouring. Ventolin tablet contains 2mg of albuterol as 2.4mg albuterol sulphate in each tablet. Source(s) of information: http://www.rxlist.com http://www.mims.com.sg Dosing and Administration: Adults and pediatric patients over 12 years of age: The usual starting dosage for adults and children over 12 years of age is 2 mg (1 teaspoonful) or 4 mg (2 teaspoonfuls) three or four times a day. Pediatric patients 6 to 12 years of age: The usual starting dosage for children 6 to 12 years of age is 2 mg (1 teaspoonful) three or four times a day. Pediatric patients 2 to 6 years of age: Dosing in children 2 to 6 years of age should be initiated at 0.1 mg/kg of body weight three times a day. The starting dosage should not exceed 2 mg (1 teaspoonful) three times a day. Dosage Adjustment Adults and pediatric patients over 12 years of age: For adults and children over 12 years of age, a dosage above 4 mg four times a day should be used only when the patient fails to respond to this dosage. If a favorable response does not occur with the 4 mg initial dosage, 93 it may be cautiously increased stepwise as tolerated, but not to exceed 8 mg four times a day (total daily dose should not exceed 32 mg). Pediatric patients 6 to 12 years of age who fail to respond to the initial starting dosage of 2 mg four times a day: For children 6 to 12 years of age who fail to respond to the initial starting dosage of 2 mg four times a day, the dosage may be cautiously increased stepwise as tolerated but not to exceed 6 mg four times a day (total daily dose should not exceed 24 mg). Pediatric patients 2 to 6 years of age who do not respond satisfactorily to the initial dosage: For children 2 to 6 years of age who do not respond satisfactorily to the initial starting dosage, the dosage may be increased stepwise to 0.2 mg/kg of body weight three times a day as tolerated, but not to exceed a maximum of 4 mg (2 teaspoonfuls) given three times a day (total daily dose should not exceed 12 mg). Elderly patients and those sensitive to beta-adrenergic stimulators: The initial dosage should be restricted to 2 mg three or four times a day. If adequate bronchodilation is not obtained, dosage may be increased gradually as tolerated to as much as 8 mg three or four times per day (total daily dose should not exceed 32 mg). Source of information: http://www.rxlist.com Side Effects / Cautions: Tremors, headaches and hyperactivity are relatively common side effects experienced. Hypersensitivity reactions such as angioedema, urticaria, bronchospasm, hypotension and collapse may occur, but are very rare. Muscle cramps or the feeling of muscle tension are possible side effects experienced when taking the tablet or syrup dosage forms. Other common side effects include chest pain, rapid heart rate and palpitations. Generally, the reactions are transient and it is not necessary to discontinue treatment. However, the dosage can be temporarily reduced and once the reaction has subsided, it can be increased by small increments to the optimal dosage. Source(s) of information: http://www.rxlist.com http://www.mims.com.sg 94 Contraindication(s): Salbutamol Syrup should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension; in patients with convulsive disorders, hyperthyroidism, or diabetes mellitus; and in patients who are unusually responsive to sympathomimetic amines. Clinically significant changes in systolic and diastolic blood pressure have been seen and could be expected to occur in some patients after use of any beta-adrenergic bronchodilator.

It can be taken by diabetic patients as it is sugar free. Source of information: DIFFLAMTM Anti-inflammatory lozenges product insert Therapeutic Classification: Other agents for local oral treatment (A01AD02) Mechanism of Action(s): Pharmacology: Benzydamine is effective against pain and oedema caused by inflammatory conditions and also inhibits granuloma formation. The analgesic activity of benzydamine is more pronounced against inflammatory than in noninflammatory pain and possesses anti-pyretic activity. Pharmacodynamics: Benzydamine inhibits the biosynthesis of prostaglandins under certain conditions. The stabilising effect on cellular membranes may also be involved in the mechanism of action. Pharmacokinetics: 117 Absorption- Benzydamine is well absorbed following oral administration into the inflamed oral mucosa where it exerts anti-inflammatory and local anaesthetics actions. Excretion- Benzydamine and its metabolites excreted largely in the urine. Source of information : MIMS Singapore (Online) Available Dosage Form(s): Solid dosage form-Lozenges Source of information: DIFFLAMTM Anti-inflammatory lozenges product insert Dosing and Administration: Strength: 3mg/lozenge How medicine should be administered: Difflam Anti-inflammatory Lozenges should not be chewed. They should be slowly dissolved in the mouth. One lozenge should be sucked slowly every one to two hours as required up to a maximum of 12 lozenges per day. Uninterrupted treatment should not exceed seven days. Source of information: DIFFLAMTM Anti-inflammatory lozenges product insert Side Effects: Most commonly reported local reaction is oral numbness, occasional burning or stinging sensation, dryness or thirst, tingling, warm feeling in mouth and altered sense of taste. Systemic adverse reactions are very uncommon, consisting mainly of nausea, vomiting, retching, gastro-intestinal disorders, dizziness, headache and drowsiness. Hypersensitivity reactions are rare but may be associated with pruritis, rash urticaria, photodermatitis and occasionally laryngospasm or bronchospasm. Cautions: Patients with impaired liver/renal function: Since absorbed benzydamine and its metabolites are highly metabolised in the liver and excreted in the urine, the possibility of systemic effects should be considered in patients with severe hepatic impairment and renal impairment. If a sore throat is either caused or complicated by bacterial infection, appropriate antibacterial therapy should be considered in addition to the use of Difflam lozenges. 118 The safety of benzydamine HCl has not been established in pregnant patients.

Mechanism of Action(s): With its large surface area and porous surface, charcoal is able to adsorb toxic substances or irritants in the gastrointestinal tract, inhibiting its absorption into systemic circulation. One of the constituents of activated charcoal is sorbitol, which induces a hyperosmotic environment in the lumen of the GI tract, causing catharsis. Charcoal also disrupts the enterohepatic circulation of bile acids, which ultimately result in the lowering of the cholesterol level. Activated charcoal adsorbs many drugs and chemicals, thus reduces the amount of the agent available for absorption. In vitro, agents that are best adsorbed are nondissociated salts and low water solubility compounds. In vivo adsorption can not always be predicted from in vitro studies, thus humans studies are needed to confirm the efficacy of activated 160 charcoal for a particular substance.
