Clozapine, an atypical neuroleptic with unique clinical and preclinical properties, represents a potentially valuable addition to the psychopharmacopeia. Its development and use have been limited by its higher frequency, compared with other pharmacologic treatments, of the potentially fatal side effect of agranulocytosis. ⋯ No patient had hematologic reactions to treatment with psychotropic agents before or after clozapine treatment. These findings, along with other work in progress, suggest that clozapine's granulocytoxic effects are produced by a highly specific immune-mediated mechanism.
