title: Pimozide versus chlorpromazine in chronic schizophrenia: a 52 week double-blind study of maintenance therapy.
abstract: This study compared the effectiveness and safety of pimozide and chlorpromazine in the maintenance therapy of chronic schizophrenic outpatients. Forty-three patients were assigned in double-blind fashion to one of the drugs for the 52 week study. Both medication groups showed a general pattern of improvement over the course of the study, but there was no significant difference between the two groups. The results demonstrated the effectiveness and safety of pimozide in once daily administration. Previous research results showing the special utility of pimozide for the improvement of emotional withdrawal and social competence in schizophrenia were not replicated.
