[Penfluridol. Results of a year-long clinical trial].

During an open clinical trial, 51 schizophrenic patients were treated with Penfluirdol, 34 for 1 year and 17 for a shorter time. The mean dosage of Penfluirdol was 22 up to 28 mg per week. Assessments were made on days 0, 14, 28, 56, 90, 180, 270, and 365 using the AMP system and the EPRS scale of Simpson and Angus. The symptomatology was mainly reduced during the first 3 months of treatment and remained afterwards relative unchanged. Penfluridol showed a good antipsychotic effect on productive schizophrenic symptoms (thought disorders and paranoid symptoms, autism and schizophrenic affective disorders). The dosage used showed only a slight sedative effect and was well tolerated concerning autonomic and extrapyramidal side-effects.
