Randomized Controlled Trial Multicenter Study Clinical TrialEfficacy and tolerability of sumatriptan tablets in a fast-disintegrating, rapid-release formulation for the acute treatment of migraine: results of a multicenter, randomized, placebo-controlled study.
Sumatriptan tablets have been developed in a fast-disintegrating, rapid-release formulation designed to facilitate tablet disintegration and drug dispersion and to potentially mitigate the effects of gastric stasis that can accompany migraine. ⋯ In this study, sumatriptan tablets in a fast-disintegrating, rapid-release oral formulation provided pain-free efficacy in the acute treatment of migraine. Efficacy was maximized with the 100-mg dose compared with the 50-mg dose, and by treating early when pain was mild. In the intent-to-treat population, 51.1% of patients who received sumatriptan 50 mg and 66.2% of those who received sumatriptan 100 mg were pain free 2 hours after dosing. In the per-protocol population, 3 of 4 patients taking the 100-mg tablets for mild pain within 1 hour of its onset were pain free at 2 hours. Sumatriptan tablets were generally well tolerated.
