Ketamine is a dissociative anesthetic primarily used for anesthesia and analgesia. It acts as an NMDA receptor antagonist and is notable for its use in both human and veterinary medicine. Ketamine has also been researched and used off-label for treatment-resistant depression and acute pain management. It is approved and in clinical use as an anesthetic agent.
