Penfluridol: a long-acting oral neuroleptic. A controlled study

The clinical promise of penfluridol as a long-acting oral antipsychotic medication has led to a number of controlled studies designed to verify its usefulness. These studies have been reviewed and compared with a controlled study carried out by the authors. The data obtained from this study have tended to confirm the impression of previous investigators that penfluridol, administered in a dosage of 40 to 80 mg on a once-a-week basis in a single dose, compares favorably with the antipsychotic activity of those neuroleptics requiring administration on a daily basis.
