Abstract
The literature on neuroleptics with substance-specific long-term effects (fluspirilene, penfluridol) is reviewed in tabular form. This is followed by a report of personal investigations on 76 schizophrenics who were treated with fluspirilene initially within the hospital and later on an out-patient basis, on 86 patients who were treated with it exclusively at the out-patients' department, as well as on 123 schizophrenic psychoses treated with penfluridol in the out-patients' department. The side-effects caused by the two substances are compared. Pre-requisites for effective long-term therapy with a few complications are discussed.
