Twenty-four patients with phencyclidine intoxication were treated with either physostigmine (2 mg i.m.) or haloperidol (5 mg i.m.) based on the presence of delusions and/or hallucinations. Several symptoms subsequently improved. Schizophreniform symptoms showed substantial improvement with haloperidol.
