Penfluridol, a long-acting oral antipsychotic, effectively treats schizophrenia, showing superiority over placebo and comparable efficacy to other typical antipsychotics. It offers a valuable, low-cost option, particularly for patients unresponsive to daily oral or depot medications.

Area of Science:

  • Psychiatry
  • Pharmacology
  • Clinical Trials

Background:

  • Penfluridol is a long-acting oral antipsychotic medication used for schizophrenia treatment since the 1970s.
  • Its once-weekly administration offers depot-like convenience.
  • This review examines its efficacy and safety in schizophrenia treatment.

Purpose of the Study:

  • To review the effects of penfluridol in schizophrenia treatment.
  • Comparison against placebo, other antipsychotics, or no intervention.

Main Methods:

  • Systematic review of randomized clinical trials (RCTs).
  • Searches included Cochrane Schizophrenia Group Register, Cochrane Central Register, and LILACS.
  • Data extracted on an intention-to-treat basis using relative risk and weighted mean differences.

Main Results:

  • Twenty-five studies with 1024 participants were included.
  • Penfluridol showed superiority over placebo in improving global state and reducing the need for additional antipsychotics.
  • No significant differences in efficacy or side effects were found compared to oral typical antipsychotics, but penfluridol had lower dropout rates than depot antipsychotics.

Conclusions:

  • Penfluridol demonstrates similar efficacy and adverse effect profiles to other typical antipsychotics.
  • It is an adequate treatment option for schizophrenia, especially for patients not responding well to daily oral or depot antipsychotics.
  • Its low cost and reduced dropout rates make it a beneficial choice for chronic schizophrenia management.
