title: Treatment of migraine attacks with intranasal alniditan: an open study.
abstract: In this open phase-II clinical tolerability trial 17 neurologists enrolled a total of 112 patients and instructed them to administer a maximum of two doses of intranasal alniditan, a 5-HT1B/D receptor agonist, for the treatment of three consecutive migraine attacks of moderate to severe intensity. A second dose of the trial medication was allowed within 1-24 h after the first administration. At 1 h after intranasal administration, 70/103 (68%) patients had responded to treatment (reduction from severe or moderate headache before treatment to mild or no headache) after their first migraine attack, 65/94 (69%) after their second and 52/75 (71%) after their third. In 187/270 (69%) of all attacks, patients were considered responders at 1 h. The median time to onset of effect was 30 min. The migraine headache recurred in 44% (attack 1), 55% (attack 2) and 44% (attack 3) after 4-5 h. Sixty-eight per cent of the patients reported nasal irritation, 19% taste disturbance and 44% throat irritation. Alniditan 2 mg, administered via the intranasal route, was effective in relieving migraine headaches in over two-thirds of the patients at 1 h.
