N2 - The ability of tonabersat to relieve the symptoms of migraine attacks with or without aura was evaluated in a randomized, double-blind, placebo-controlled, multicentre, parallel-group study. Patients received 20 or 40 mg of tonabersat, or 50 mg of sumatriptan (positive control), or placebo at the onset of a moderate or severe attack. Headache intensity, relief and recurrence were recorded for 24 h after dosing. On the basis of primary or secondary efficacy measures, tonabersat did not provide a clinically or statistically significant advantage over placebo. Tonabersat generally was well tolerated and had no effect on vital signs, electrocardiogram recordings or laboratory values. The lack of efficacy may be a function of the slow absorption of tonabersat. As a consequence of slow absorption, daily administration of tonabersat as prophylaxis for migraine attacks is under investigation in ongoing studies.
