Explanation / Answer

Ketamine is a drug used in human and veterinary medicine, primarily for the induction and maintenance of general anesthesia, usually in combination with a sedative. Other uses include sedation in intensive care, analgesia (particularly in emergency medicine), and treatment of Bronchospasm. Ketamine has a wide range of effects in humans, including analgesia, anesthesia, and hallucinations, elevated blood pressure, and bronchodilator.[2] Like other drugs of its class, such as tile amine and phencyclidine (PCP), ketamine induces a state referred to as "dissociative anaesthesia"[3] and is used as a recreational drug.

Ketamine can be effective in treating depression in patients with depression and bipolar disorder who have not responded to antidepressants.[4] It produces a rapid antidepressant effect, acting within two hours as opposed to the several weeks taken by typical antidepressants to work.[5]

Its hydrochloride salt is sold as Ketanest, Ketaset, and Ketalar. Pharmacologically, ketamine is classified as an NMDA receptor antagonist.[6] At high, fully anesthetic level doses, ketamine has also been found to bind to ?-opioid receptors type 2 in cultured human neuroblastoma cells
