Ketamine is classified as which type of drug?

Explanation:
Ketamine is a dissociative anesthetic that does not act on opioid receptors, so it is categorized as a non-opioid. Its effect comes from antagonism of NMDA receptors, which provides anesthesia and analgesia with dissociation rather than the typical opioid-mediated pain relief. While it can produce sedation, its primary pharmacologic classification isn’t a sedative, and calling it an “antagonist” refers to its mechanism (NMDA receptor blockade) rather than a broad drug class. For these reasons, the best way to classify ketamine among the options is as a non-opioid.
