Clozapine: a clinical review of adverse effects and management.

Clozapine (Clozaril) is a novel and unique prototype atypical, tricyclic, dibenzodiazepine-derivative, antipsychotic agent. It has been proven effective and significantly superior to placebo, as well as to conventional neuroleptics, in several placebo-controlled, double-blind studies in treatment-resistant schizophrenia. It has also been found to produce an incidence of extrapyramidal symptoms (EPS) as low as that found with placebo.
