Phencyclidine receptor

WebPhencyclidine or 1- (1-phenylcyclohexy-1) piperidine (known as PCP, “angel dust”, and many other names) was originally developed as an anesthetic, but was abused as an illicit drug from the late 1960s onwards. It is a dopamine receptor agonist and an antagonist at the N-methyl-d -aspartate (NMDA) subtype of glutamate receptors. WebPhencyclidine (PCP) and ketamine are dissociative anesthetics that work by binding to the brain's inhibitory neurotransmitter receptors. Because PCP and ketamine have such a rapid onset and short duration of action, they are commonly abused, and their recreational use is often referred to as "hippie-dip". However, unlike other dissociative ...
