Abstract

Topiramate is approved for the preventive treatment of migraine in several countries based on the results of three large randomised, double-blind studies that showed that this compound was significantly more effective than placebo in migraine prophylaxis. We review the results of two studies: one which pooled data from the three controlled double-blind trials using 100 mg/day of topiramate, and an open-label extension of two of these trials in which patients received different topiramate doses for an eight-month maintenance period. The overall results confirm that topiramate is effective in reducing migraine frequency, and has a satisfactory tolerability profile.

How strong is the evidence?

Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
