Fluperlapine is dibenzazepine chemically and pharmacologically similar to clozapine. Fluperlapine had no cataleptogenic effect and did not inhibit the apomorphine- and d-amphetamine-induced stereotypes. Fluperlapine is fairly effective neuroleptic drug with a fast-acting antipsychotic affect. The effects in movement disorders imply that fluperlapine is less liable than traditional neuroleptics to induce acute extrapyramidal side effects and tardive dyskinesia and is particularly beneficial in the treatment of patients vulnerable to neurological side-effects. It was demonstrated efficacy in the treatment of a variety of medical conditions including schizophrenia, psychosis associated with Parkinson's disease and dystonia. It has the capacity for producing life-threatening agranulocytosis.
