A previously published, placebo-controlled, head-to-head comparator study found eletriptan to have superior efficacy to oral sumatriptan 100 mg in treating a single acute migraine attack. The goal of the current study was to extend the findings of that study by examining the efficacy of eletriptan compared with both 50- and 100-mg doses of sumatriptan; and to evaluate the comparative efficacy of eletriptan and sumatriptan across additional important clinical outcomes. In particular, early response (at 1 hour), sustained response (without need for additional treatment) at 24 hours, and consistency of response across multiple attacks were examined.
