The patient was suffering more from nausea than from pain. Her physician had prescribed antiemetic trimethobenzamide suppositories (Tigan) 200 mg to be used every 6 to 8 hours as needed, but this medication did not relieve the nausea. As a pharmacist, I meet weekly with a hospice care interdisciplinary team for the purposes of assessing and determining treatments for terminally ill patients. At our meeting on March 15, 2000, I suggested that a topical Ativan, Benadryl, and Haldol (ABH) gel to which pentoxifylline had been added be prescribed to alleviate this patient’s nausea, and her physician agreed. ABH gel is a combination formula mixed in a Pluronic lecithin organogel in the following concentrations: lorazepam (Ativan) 1 mg/mL diphenhydramine (Benadryl) 25 mg/mL haloperidol (Haldol) 1 mg/mL pentoxifylline (Trental) 50 mg/mL (to enhance absorption) The patient was instructed to apply 1 mL of this gel to her wrist every 4 to 6 hours as needed. At the time of our interdisciplinary team meeting on March 29, 2000, the patient was still experiencing some nausea. I suggested adding metoclopramide (Reglan) in a 10-mg/mL concentration to the gel; the dose (a topical application of 1 mL every 4 to 6 hours) was to remain unchanged. After 2 doses of treatment with this formulation, the patient’s nausea was relieved. She continued this protocol and experienced relief from nausea until her death in late April 2000. We have found this combination of topically applied medication to be very effective in decreasing the anxiety and nausea produced by some diseases during the endof-life process. Suggested Reading 1.

Der maZinc-Plus with Clobetasol for the Treatment of Psoriasis David Holloway, RPh Trail Creek Pharmacy, Euless Texas In late April 2000, a 32-year-old man became the patient of a physician located close to our pharmacy. In 1995, the patient had been diagnosed as having psoriasis, for which he had been treated by several physicians. When the patient received his diagnosis, his family history indicated that no other relatives had psoriasis, but the condition was subsequently diagnosed in his aunt and in his grandfather. The psoriatic lesions first appeared on the patient’s elbow as a scaling sore that did not heal, and in 1997 the lesions appeared on his scalp. He had been treated with a number of agents, including betamethasone lotion 0.05% (Diprolene), calcipotriene topical solution 0.005% Continued on Reverse. Literature Summary Intranasal Fentanyl Citrate and CancerRelated Breakthrough Pain An assessment of the safety, efficacy, and acceptability of intranasal fentanyl citrate in the management of cancer-related breakthrough pain: A pilot study. Source: Zeppetella G. J Pain Symptom Manage 2000;20:253-258. Breakthrough pain is a common problem, especially for patients who are undergoing treatment for cancer. This type of pain, which afflicts patients despite the use of concomitant analgesic therapy, often occurs frequently and is brief in duration and severe or excruciating in intensity. According to the author of the study cited above, an analgesic with the following attributes would be of benefit in treating patients experiencing breakthrough pain: rapid absorption, an “individual and episodic titration,” a rapid onset of action, and a short-to-moderate duration. Intranasally administered medications offer those advantages. The study described in the article by Zeppetella consisted of 12 hospice patients (average age, 73 years) who were experiencing one type of nociceptive cancer-related breakthrough pain (which is usually responsive to opioids) for which pain management was required. In nine of those patients (75%), the site of the break- the system of delivery. The author notes that before the study, the subjects had been receiving oral morphine, which requires approximately 1 hour to achieve maximum concentration and produces analgesia for a duration of about 4 hours. Because breakthrough pain may occur several times per day for short periods, the effects of short-acting morphine used as a rescue medication may continue beyond the duration of pain; repeated dosing can result in adverse effects. Parenterally administered opioids used when rapid pain relief is required have many disadvantages for the patient: Their administration is invasive and uncomfortable. However, INFC can be rapidly, easily, and painlessly absorbed through the nasal mucosa and, because it has a low toxic effect on local tissue, it can be used as long-term therapy. It is delivered as a bolus dose to the site of absorption and becomes effective within 10 minutes of administration. The author suggests that INFC may have additional applications in the treatment of neuropathic pain and during painful treatment procedures. Because INFC was well-tolerated and well-received by most of the subjects, he recommends that additional studies be conducted to determine the role of that therapy in the management of cancer-related breakthrough pain.

The average number of daily pain episodes was five, and 50% of the subjects rated the pain as being severe or excruciating. In eight patients (66.6%), the pain lasted 30 minutes or less. At the time of the study, all subjects had been receiving morphine in various protocols (listed in Table 2 of the article) as regular analgesia and were also using short-acting oral morphine (on average, twice per day) for breakthrough pain. Relief from breakthrough pain provided by morphine was rated as “good” by four patients (33%), “fair” by five (42%), and “poor” by three (25%). At the initiation of the study, each patient began a protocol of receiving 20 µg of intranasally administered fentanyl citrate (INFC) from a 10-mL nasal spray bottle with a 0.2-mL reservoir. Each spray bottle delivered a 0.2-mL bolus dose with each spray. This treatment with INFC was to replace treatment with short-acting oral morphine, which had been used as the rescue medication before the study. If the breakthrough pain was completely relieved by one spray, patients were to continue with that dosage. If partial relief or no pain relief resulted, each patient was given a second bottle to provide sufficient drug to spray both nostrils. All patients required two bottles of the preparation. Patients were asked to use the INFC spray for five consecutive occurrences of breakthrough pain. The degree of pain was assessed by means of a visual analogue scale (VAS) before treatment with INFC and 3, 5, 10, 15, 30, 45, and 60 minutes after the administration of that medication. Nonbreakthrough analgesics that were taken before the trial were continued without change in the dose. During the study, patients were monitored for adverse events. At the conclusion of the trial, the subjects were asked whether they had experienced adverse events and how they rated the pain-management efficacy of INFC. Each subject was also asked to list the advantages and disadvantages of taking medication to control pain. After treatment with INFC, eight patients (66%) demonstrated a reduction in the VAS score. Four of those patients noted a reduction in pain 5 minutes after having used INFC, and seven patients noticed pain relief after 10 minutes. Those eight patients rated the efficacy of INFC as “good” or “very good.” Nine patients (75%) indicated that INFC was as effective as or better than morphine, and four (33%) rated the effectiveness of INFC as “moderate” or “bad.” According to the author, patients who had been receiving the lowest daily doses of morphine showed a decline in the VAS score after treatment with INFC, and those who had been receiving a daily morphine equivalent of 120 mg or more did not. During the study, two patients required their usual rescue doses of short-acting morphine in spite of taking INFC, and two patients suffered from nasal discomfort and nasal itching when they began to use INFC, but those symptoms disappeared as the drug was used repeatedly. No systemic adverse events as a result of treatment were noted. At the conclusion of the study, nine patients (75%) said that they would continue treatment with INFC, and the remaining subjects were dissatisfied with the effectiveness of the preparation rather than PL (Dovonex), and fluocinolone topical solution (Derma-Smoothe/FS). The patient’s primary complaint was that psoriatic lesions covered 25% to 50 % of his scalp. His physician prescribed a zinc pyrithione formula with clobetasol propionate 0.05% (DermaZinc-Plus) in a 120mL spray bottle. The medication was to be applied twice daily. DermaZinc is an overthe-counter preparation used twice a day to maintain normal skin in patients with psoriasis. When severe flare-ups occur, the patient is usually switched to the DermaZinc-Plus, which must be applied for approximately 2 weeks or as directed by a physician. This preparation becomes a compounded prescription-strength formula when clobetasol is added. Our patient, like many others with psoriasis, required multiple therapies in order to restore his skin back to normal condition. In addition to treatment with the spray, ketoconazole shampoo (Nizoral) and an over-the-counter coal tar shampoo were prescribed to be alternated in use every other day, and the patient was to receive ultraviolet light treatment for 10-to-15 minutes from a tanning bed 2 times a week. After 5 months of following this regimen, the patient was doing well and his psoriasis had completely resolved. When he used a different shampoo, however, the psoriatic lesions recurred within a month. At the time of this writing, he is continuing his maintenance therapy with the zinc pyrithione -clobetasol propionate spray, the ketoconazole and coal tar shampoos, and the ultraviolet light therapy and is doing very well. Legal Update Compounding Law Rescinded In 1997 Congress passed a compounding law as part of the Federal Food and Drug Administration Modernization Act of 1997 (FDAMA). A section of this compounding law relating to advertising was challenged for its constitutionality during the last three years. On Tuesday, February 6, 2001, the 9th Circuit Court of Appeals ruled that the government’s restrictions that prohibit compounding pharmacists from advertising are unconstitutional. In Western States Medical Center v. Shalala, a case brought by a group of licensed pharmacies, the court found that the advertising provision was not severable from the compounding section of the law and therefore declared the entire compounding law invalid. In its opinion, the Court stated that the FDA failed to prove that they have a substantial interest in preventing widespread compounding. They stated that FDA fails to support the opinion that increased distribution of compounded drugs is dangerous because of the health risks associated with large numbers of patients taking such drugs. The decision states that most evidence runs to the contrary noting that compounding is legal under state law and that most states require pharmacists to know how to compound. In essence, FDA failed to prove that compounding is unsafe and should be limited. Pharmacists are licensed and regulated by state boards of pharmacy. Most states have laws specifically setting forth parameters for pharmacy practice. In addition, the National Association of Boards of Pharmacy has published a model act for states to adopt to regulate compounding practice and the United States Pharmacopeia has created an entire chapter on professional compounding practice for pharmacists to reference. Although the implication of the court’s decision is unclear from regulatory standpoint, the practice of compounding as necessary was clearly upheld.
