Phencyclidine

n. anesthetic and hallucinative drug, PCP (known as "angel dust")

Phencyclidine (a contraction of the chemical name phenylcyclohexylpiperidine), abbreviated PCP, is a dissociative drug formerly used as an anesthetic agent, exhibiting hallucinogenic and neurotoxic effects.It was first patented in the 1950s by the Parke-Davis pharmaceutical company. PCP is listed as a Schedule II drug in the United States under the Convention on Psychotropic Substances.Chemically PCP is an arylcyclohexylamine derivative, and pharmacologically, it is a member of the family of dissociative anesthetics. PCP works primarily as an NMDA receptor antagonist which blocks the activity of the NMDA Receptor. Other NMDA receptor antagonists include ketamine, tiletamine, and dextromethorphan. Although the primary psychoactive effects of the drug only last hours, total elimination from the body is prolonged, typically extending over weeks.
