Summary

In a double-blind trial, 34 male chronic schizophrenic day-patients or in-patients in a hostel ward continued on fluphenazine decanoate given mostly once fortnightly or were switched to pimozide, given on four days each week. Over nine months relapse rates were similar for both groups, and while fewer patients on pimozide were prescribed antiparkinsonian drugs one quarter developed buccolingual-masticatory dyskinesia. Plasma pimozide levels suggested satisfactory drug compliance. Average plasma prolactin levels were within the normal range for untreated men in one quarter of non-relapsing patients on pimozide and three quarters on fluphenazine.
