Twenty-three patients who completed a four-week, double-blind, clinical trial of bromperidol versus haloperidol were treated with bromperidol for eight additional weeks in a continuation study. Over 87 percent of patients maintained their improved status or showed further improvement. Extrapyramidal signs were frequent, but required discontinuation of treatment in only two patients.
