title: Extrapyramidal side effects in chlorpromazine recipients: emergence according to benztropine prophylaxis.
abstract: The frequency of extrapyramidal symptoms (EPS) attributed to chlorpromazine among 86 patients who received benztropine for the prevention of EPS (9.3%) was similar to that of the 568 patients who received chlorpromazine alone (10.6%). The data in this small sample indicated that the prophylactic use of benztropine had no effect in reducing the rate of EPS.
