title: Clozapine in the treatment of parkinsonian patients with dopaminomimetic psychosis.
abstract: In a double-blind placebo-controlled study, we evaluated the effects of clozapine (75 to 250 mg/day, mean 170.8) on dopaminomimetic psychosis and parkinsonian disability. Clozapine prevented deterioration of psychosis during the increase of dopaminomimetics in the 3 patients who completed the study. Worsening of parkinsonism occurred in 3 of the 6 patients. In the dosage used, clozapine's usefulness was limited by its propensity to produce sedation, confusion, and increased parkinsonism.
