The impact of migraine prevention on daily activities: a longitudinal and responder analysis from three topiramate placebo-controlled clinical trials

Abstract

Abstract Background Topiramate is approved for the prophylaxis (prevention) of migraine headache in adults. The most common adverse events in the three pivotal, randomized, double-blind, placebo-controlled trials were paresthesia, fatigue, cognitive impairment, anorexia, nausea, and taste alteration. In these trials, topiramate 100 mg/d significantly improved Migraine-Specific Questionnaire (MSQ) scores versus placebo (p Methods Mean MSQ and Medical Outcome Study Short Form 36 (SF-36) change scores (baseline to each double-blind assessment point) were calculated for pooled intent-to-treat (ITT) patients. Additionally, pooled ITT patients receiving topiramate 100 mg/d or placebo were combined and divided into two responder groups according to percent reduction in monthly migraine frequency: Results Of 756 patients (mean age 39.8 years, 86% female), 384 received topiramate 100 mg/d and 372 placebo. Topiramate significantly improved all three MSQ domains throughout the double-blind phase versus placebo (p = 0.024 [week 8], p Conclusion Topiramate 100 mg/d significantly improved daily activities and patient functioning at all time points throughout the double-blind phase. Daily function and health status significantly improved for those achieving a ≥ 50% migraine frequency reduction.
