Which statement about PCP is true?

• A. It is a Narcotic
• B. It is a Depressant
• C. It is a Dissociative Anesthetic
• D. It is a Stimulant

Answer: (C)

PCP is best described as a dissociative anesthetic. Dissociatives produce a sense of detachment from the surrounding environment and from one’s own body, often with analgesia and distorted perception of time and space. PCP achieves this mainly by blocking NMDA receptors in the brain, which disrupts normal communication between brain regions involved in perception and sensation. This distinguishes it from narcotics (opioids), which act on opioid receptors and have a different profile of effects and dependence; from depressants, which slow brain activity and respiration; and from stimulants, which primarily increase alertness and energy. PCP's effects can include agitation, impaired coordination, nystagmus, tachycardia, and hypertension, and at high doses, seizures or coma, but its defining classification is as a dissociative anesthetic.
