title: Benztropine prophylaxis of dystonic reactions.
abstract: The effectiveness of antiparkinson medication for the prevention of drug induced dystonias has remained a question. Forty patients with acute psychosis who received high potency oral antipsychotic drugs were interviewed to determine the incidence of acute dystonia. An eleven-fold increase in dystonia was found in patients who received no prophylactic medication. Such prophylaxis appears effective in preventing acute dystonia.
