Abstract
Flunarizine is a class IV calcium antagonist with a pharmacological profile which suggests its therapeutic potential in a number of neurological and cerebrovascular disorders. It is an effective prophylactic treatment for common or classic migraine in children and adults, and it appears at least as effective as a number of other agents which act by different pharmacological mechanisms, including pizotifen (pizotyline), cinnarizine, methysergide, nimodipine, metoprolol, propranolol, aspirin and cyclandelate. Flunarizine is also effective in reducing the frequency of seizures, when used as an 'add-on' treatment, in some patients with partial or generalised epilepsy resistant to maximal therapy with a combination of several conventional antiepileptic drugs. Placebo-controlled studies show that flunarizine is effective in the treatment of vertigo and associated symptoms of either peripheral or central origin, and in the treatment of cerebrovascular insufficiency where psychological symptoms, rather than vertigo, are the primary symptoms. In the treatment of vertigo, flunarizine appears at least as effective as cinnarizine and more effective than nicergoline, betahistine dichlorhydrate, pentoxifylline (oxpentifylline) and vincamine. Flunarizine therefore is useful in the prophylaxis of migraine, an effective treatment for vertigo and a worthwhile alternative as 'add-on' therapy in patients with epilepsy resistant to conventional drugs.
