Evaluation of penfluridol in hospitalised chronic schizophrenic.

Thirty chronic schizophrenic patients completed 12 week treatment with a single weekly dose of 20 mg penfluridol, a new long acting oral neuroleptic. The patients were evaluated by using modified rating scale. Significant reduction in scores was demonstrated in 15 out of 26 symptom variables. Few side effects were reported which were easily controlled by conventional antiparkinson agents. Laboratory investigations remained within normal limits.
