Randomized Controlled Trial Multicenter Study Clinical Trial
Alniditan in the acute treatment of migraine attacks: a subcutaneous dose-finding study. Subcutaneous Alniditan Study Group.
Alniditan is a new 5HT1D receptor agonist, belonging to a different chemical class from sumatriptan and other indole derivatives used or being developed for the treatment of acute migraine. In a multinational double-blind randomized parallel-groups dose-finding trial, alniditan was given subcutaneously in hospital to patients with migraine headache of moderate or severe intensity at doses of 0.8 mg (n = 44), 1.0 mg (n = 42), 1.2 mg (n = 46) and 1.4 mg (n = 39). Efficacy, tolerability and safety of each dose were compared with those of placebo (n = 41). ⋯ Adverse effects, mainly head pressure, paraesthesia, and hot flushes, were reported by 34% of placebo-treated patients and up to 70% of patients receiving alniditan, but all doses were very well tolerated and no clear relationship with dose was established. Comparison with published findings suggests that alniditan 1.4 mg sc may have advantages over sumatriptan 6 mg sc in providing complete relief from acute migraine headache, and may be associated with fewer headache recurrences within 24 h. Both of these suggestions warrant further and larger trials of alniditan in acute migraine.
