Clinical Information

Phencyclidine (PCP) affects diverse neural pathways and interacts with cholinergic, adrenergic, gamma-aminobutyric acid (GABA) secreting, and serotoninergic receptors, as well as opiate neuronal receptors and gamma receptors while its principle psychoactive effects are thought to come from its inhibitory effects on the N-methyl-D-aspartate (NMDA) receptor. It has analgesic, anesthetic, and stimulatory effects, giving bizarre behavior, ranging from depression through catatonia, euphoria, violent rage, and hallucinations. Most fatalities result from its hypertensive effect.
