Abstract | OBJECTIVE: BACKGROUND: METHODS: This randomized, double-blind, placebo-controlled, parallel group study enrolled adults with migraine pain as per International Headache Society criteria. Subjects took tramadol/ APAP (total dose, 75 mg/650 mg) or placebo for a typical migraine with moderate-to-severe pain. Severity of pain and migraine-related symptoms were recorded before study medication and at 0.5, 1, 2, 3, 4, 6, and 24 hours after study medication. RESULTS: Efficacy analyses included 305 subjects (154 tramadol/ APAP and 151 placebo). Treatment response was higher for tramadol/ APAP than a placebo at 2 hours after dosing (55.8% vs. 33.8%, P < .001) and at every other assessment from 30 minutes (12.3% vs. 6.6%) through 6 hours (64.9% vs. 37.7%) (all P< or = .022). Subjects in the tramadol/ APAP group were more likely than those in the placebo group to be pain-free at 2 hours (22.1% vs. 9.3%), 6 hours (42.9% vs. 25.2%), and 24 hours (52.7% vs. 37.9%) (all P< or = .007). Two hours after dosing, moderate-to-severe symptoms that were less common for tramadol/ APAP than placebo included photophobia (34.6% vs. 52.2%, P= .003) and phonophobia (34.3% vs. 44.9%, P = .008), but not migraine-related nausea (38.5% vs. 29.4%, P= .681). Treatment-related adverse events included nausea, dizziness, vomiting, and somnolence. CONCLUSIONS:
