Although there are shortcomings and gaps in the data, there appears to be enough overall consistency for different outcomes. The efficacy and adverse effects profile of penfluridol are similar to other typical antipsychotics; both oral and depot. Furthermore, penfluridol is shown to be an adequate treatment option for people with schizophrenia, especially those who do not respond to oral medication on a daily basis and do not adapt well to depot drugs. One of the results favouring penfluridol was a lower drop out rate in medium term when compared to depot medications. It is also an option for chronic sufferers of schizophrenia with residual psychotic symptoms who nevertheless need continuous use of antipsychotic medication. An additional benefit of penfluridol is that it is a low-cost intervention.

Penfluridol maintenance therapy in schizophrenia: a controlled study.
Twenty eight chronic schizophrenics were assigned in a double blind fashion to treatment with penfluridol or placebo for a period of 12 weeks. The clinical picture including the side effects were monitored regularly, whenever the clinical picture deteriorated haloperidol in individually adjusted doses was added to the treatment regimen. By the end of the study 12 out of the 14 placebo patients required haloperidol as compared to only 1 of the 14 penfluridol patients. Evaluation of the results showed no significant differences between the two groups or between the baseline and the final ratings in each group. This trial has confirmed the previous reports that penfluridol is a suitable drug for maintenance therapy in schizophrenic patients.
