A double-blind, placebo-controlled study examined topiramate at a dosage of about 100 mg/day, and concluded that it may be safe and effective in decreasing Total Tic Score, but noted that a larger study with longer followup than their 10 weeks was needed. [179] However, a Chinese meta-analysis of 9 randomized controlled trials did not show significant difference in reducing tic occurrence between topiramate and haloperidol or tiapride. [180]
