Treatment of Phenylcyclohexylpyrrolidine (Php) Psychosis with Haloperidol

Abstract

Twenty white males who presented with psychosis were later found to have ingested PHP. Treatment with haloperidol 5 mg IM caused significant improvement while placebo treatment did not. Results of haloperidol treatment of PHP psychosis were similar to previously published reports with phencyclidine (PCP) psychosis.
