Psychopharmacologists classify ketamine as a:

• A. Benzodiazepine—a Sedative/Hypnotic
• B. Narcotic
• C. Dissociative Anesthetic
• D. Stimulant

Answer: (C)

Ketamine is classified as a dissociative anesthetic. This means it produces a trance-like state with analgesia, sedation, and memory loss while often maintaining airway reflexes, which sets it apart from typical sedative-hypnotics like benzodiazepines. It differs from narcotics (opioids), which primarily relieve pain and can depress respiration, and from stimulants, which increase alertness and activity. The dissociative effect comes from ketamine’s action as an NMDA receptor antagonist, disrupting communication between brain networks and creating a sense of detachment from the environment. This combination of anesthesia with dissociation is why it’s labeled a dissociative anesthetic.
