    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 < 0.001). The MSQ measures how much migraine limits/interrupts daily performance. Pooled analyses of pivotal trial data were conducted to further assess how topiramate 100 mg/d affects daily activities and patient functioning. 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: < 50% responders or >or= 50% responders. Between-group differences were assessed using analysis of covariance. 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 < 0.001 [weeks 16 and 26] for role prevention; p < 0.001 for role restriction and emotional function [all time points]). Topiramate 100 mg/d significantly improved SF-36 physical component scores (PCS) throughout the double-blind phase versus placebo (p < 0.001, all time points) and significantly improved mental component scores (MCS) at week 26 (p = 0.043). The greatest topiramate-associated improvements on SF-36 subscales were seen for bodily pain and general health perceptions (p < 0.05; weeks 8, 16, and 26), and physical functioning, vitality, role-physical, and social functioning (p < 0.05; weeks 16 and 26). Significantly greater improvements in all three MSQ domains, as well as the PCS and MCS of SF-36, were observed for >or= 50% responders versus < 50% responders (p < 0.001). Significantly greater percentages of topiramate-treated patients were >or= 50% responders versus placebo (46% versus 23%; p < 0.001). 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 >or= 50% migraine frequency reduction.
