Ketamine

Ketamine is a dissociative anesthetic for use in human and veterinary medicine developed by Parke-Davis (1962). Its hydrochloride salt is sold as Ketanest, Ketaset, and Ketalar. Pharmacologically, ketamine is classified as an NMDA receptor antagonist, and, like other drugs of this class such as tiletamine, and phencyclidine (PCP), induces a state referred to as "dissociative anesthesia." As with other pharmaceuticals of this type, ketamine is used illicitly as a recreational drug, sometimes referred to as Special K.
