    Abstract:
    OBJECTIVE: To determine if administration of rizatriptan 10 mg is superior to placebo for the early treatment of acute migraine, while the pain is mild. BACKGROUND: Past studies have suggested that treatment outcomes can be improved if a triptan is administered early in the time course of a migraine attack. METHODS: Two randomized, parallel, placebo-controlled, double-blind studies. TAME (Treat A Migraine Early)1 was conducted at 46 centers in the United States; TAME2, at 48 centers in the United States. Totally, 1030 adult patients with at least a 6-month history of migraine were studied. Patients were instructed to treat within 1 hour of migraine onset, while pain was mild. Patients maintained a headache diary in which they rated their levels of pain and disability, and recorded other symptoms of migraine. Primary endpoints were pain freedom at 2 hours and sustained pain freedom at 24 hours post-dose. RESULTS: In TAME1, 57.3% versus 31.1% of patients reported pain freedom at 2 hours post-dose and 42.6% versus 23.2% reported 24-hour sustained pain freedom with rizatriptan versus placebo, respectively (P < .001 for both). In TAME2, 58.9% versus 31.1% of patients reported pain freedom at 2 hours post-dose and 48.0% versus 24.6% reported 24-hour sustained pain freedom with rizatriptan versus placebo, respectively (P < .001 for both). All other efficacy endpoints favored rizatriptan. Repeat doses of the medicine were not allowed; patients may have delayed treatment; non-migraine headaches may have been treated. CONCLUSIONS: Rizatriptan 10 mg was superior to placebo when treating migraine early, while pain is mild, as measured by pain freedom at 2 hours and 24-hour sustained pain freedom.
