In a double-blind study the therapeutic effect and tolerance of pizotifen was compared with placebo in 20 outpatients of both sexes suffering from light to moderate depression. Pizotifen seems to possess certain antidepressive effects in dosages of 4-10 mg daily. These properties, and the well-documented effect of pizotifen in migraine, could make it an alternative in treating patients suffering from the often seen combination of vascular headache/depression.

The serotonin antagonist pizotifen (BC-105) is prescribed as an appetite and weight enhancer (Mosegor--Wander, also commercialized under brand names Sanmigran or Sandomigran--Sandoz, Switzerland) for anorectic and convalescent humans. There has been, however, difficulty in demonstrating any orexigenic effect of pizotifen in laboratory animals. In the present report, the influence of chronic administration of pizotifen (0.1-30.0 mg/kg b.wt. per day, SC) on food intake and body weight gains was studied in rats given a standard diet (SD-energy content 14.5 kJ/g, 9% fibre), and in rats either habituated to a low energy content, carbohydrate-free diet (DD-7.3 kJ/g, 45% fibre), or given the DD after habituation to the SD. Pizotifen failed to increase food intake or weight gain. Nor did it shorten a period of initial depression of intake of the unfamiliar DD. On the contrary, pizotifen seemed to diminish food intake and weight gain in rats fed the low energy content diet. Since it has been reported that other 5-HT antagonists, e.g., cyproheptadine, methysergide, and ritanserin can enhance feeding, it is of some interest that pizotifen failed to affect food intake or weight gain in rats. The results suggest that the effects of pizotifen (and, possibly, of serotonin) in rats may differ from those in man. The possibility that feeding in the rat is mediated by 5-HT1 rather than 5-HT2 receptors is discussed.

Migraine prophylaxis is a stepwise procedure with lifestyle advice followed by consideration of medications. Patients should be advised to try to maintain a regular lifestyle, with regular sleep, meals, exercise, and management of stress, perhaps through relaxation techniques or other ways that are sensible for them. If this regimen does not adequately control their migraines, preventatives are indicated. Patients can choose between evidence-based nutraceuticals such as riboflavin, feverfew, butterbur, or coenzyme Q10, or more traditional pharmacotherapeutics. Medicine choices are somewhat limited by what is available in each country, but from the full range, the medicines of first choice are beta-adrenoceptor blockers, flunarizine, topiramate, and valproic acid. Beta-adrenoceptor blockers are particularly useful in patients also suffering from hypertension or tachycardia. Following recent studies, topiramate has become a first choice for episodic as well as chronic migraine. It is the only prophylactic drug that may lead to weight loss, but it is sometimes associated with adverse cognitive effects. Valproic acid and flunarizine also have very good prophylactic properties. However, valproic acid is often associated with adverse effects, and flunarizine is unavailable in many countries, including the United States. If sequential monotherapies are ineffective, combinations of first-line drugs should be tried before advancing to drugs of second choice, which are associated with more adverse effects or have less well-established prophylactic properties. Amitriptyline should be used carefully because of its anticholinergic effects, although it is useful in comorbid tension-type headache, depression, and sleep disorders. Methysergide is very effective, but it has been supplanted or even made unavailable in many countries because of its well-described association with retroperitoneal fibrosis. Pizotifen has a slightly better safety profile but is unavailable in the United States. Aspirin is particularly useful in patients needing platelet inhibitors for other medical conditions, but the risk of gastrointestinal bleeding must be considered. The prophylactic properties of magnesium, riboflavin, and coenzyme Q10 are low at best, but their lack of severe adverse effects makes them good treatment options. Magnesium may be particularly useful during pregnancy. Lisinopril and candesartan were shown to be effective in single trials and are preferable in patients with hypertension. Acupuncture may be another alternative; although controlled trials have failed to differentiate its effect from placebo, it is at least innocuous. Botulinum toxin A is not effective in the prophylaxis of episodic migraine.
