Physostigmine and haloperidol treatment of acute phencyclidine intoxication
S Castellani, AJ Giannini and PM Adams
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.
