Clinical experience with clozapine in Germany.
The so-far successful development of the atypical neuroleptic clozapine had been interrupted by the Finnish epidemic of agranulocytosis in 1975. However, though the strong regulatory control of prescribing clozapine, since then its clinical use has increased steadily, particularly recently. This may be due mainly to the considerable number of patients whose psychotic states or at least whose negative symptoms do not respond to other neuroleptics, or who have problems with extrapyramidal side effects. Due to its significant antipsychotic, and to its probable even if mild antidepressive efficacy as well as to its possible efficacy against some negative symptoms of schizophrenia, clozapine is currently a real and indispensable alternative to other existing neuroleptics. Further research should be directed both to the clinical validation of the latter mentioned therapeutically desired effects and to the causes and predictability of agranulocytosis, as yet the main risk of clozapine therapy. Theoretically profitable would be the clarification of the causes of hyperthermia and particularly of those of the mutual independency of extrapyramidal motor disturbances and antipsychotic efficacy.
