Input: Six randomized controlled trials were included (total 162 participants, age range 7 to 53 years).  Pimozide was compared with: placebo and haloperidol (two trials), placebo (one trial), haloperidol (one trial), and risperidone (two trials). Methodological quality was rated ‘fair’ for all studies. Studies used different outcome measurement scales for assessing tic severity and adverse effects. Significant clinical heterogeneity made meta-analysis inappropriate. Pimozide was superior to placebo in three studies, though it caused more side effects than placebo in one of these. Pimozide was inferior to haloperidol in one of three studies (the other two showed no significant difference between the drugs), which also showed significantly fewer side effects associated with pimozide. No significant differences between pimozide and risperidone were detected. Pimozide is an effective treatment for tics in Tourette Syndrome, though the number of trials comparing its effect to placebo and other drugs is limited. Trials of longer duration (minimum six months) are needed to investigate the longer-term effects of pimozide compared to atypical neuroleptics.  Future trials should use the Yale Global Tic Severity Scale to assess the main outcome measure, and quantify adverse events with the Extrapyramidal Symptoms Rating Scale.
Output:

The review authors searched the medical literature for clinical trials that compared pimozide to other drugs, or a dummy drug (placebo), for treating tics in patients with Tourette Syndrome. The trials identified showed that pimozide was more effective at reducing tics than placebo. It was slightly less effective than the drug haloperidol, but showed fewer side effects. There were no important differences between pimozide and risperidone for either reduction of tics or side effects. In future, if trials could be run for longer, it would help the investigation of the nature of side effects caused by these drugs.
