Abstract

Phencyclidine (PCP), a widely abused drug currently, has multiple pharmacological actions, including psychotomimetic [1], anesthetic [2], sympathomimetic [2], anticholinergic [3-7], and dopaminergic [8-10]. Similarly, PCP intoxication in man can present with diverse symptoms: schizophrenia-like delusions and hallucinations; mania; violence, dyskinetic, catatonic, or stereotyped movements; hypertension; and coma [11, 12]. There is general agreement that the treatment of PCP intoxication includes support of vital functions and acidification of the urine [13]. However, there is no known specific antidote for PCP toxicity. Although diazepam [13], haloperidol [14, 15], and chlorpromazine [16] have been reported to improve the agitation and psychotic symptoms caused by PCP, the therapeutic efficacy of these agents has rarely been documented with objective clinical measures. Recently we found that intramuscular physostigmine and haloperidol [17, 18] improved several symptoms of acute PCP intoxication as measured by the Brief Psychiatric Rating Scale (BPRS) [19].
