Ketamine is a rapid-acting general anesthetic and NMDA receptor antagonist used for induction of anesthesia diagnostic and surgical procedures typically in combination with a muscle relaxant.
Ketamine interacts with N-methyl-D-aspartate (NMDA) receptors, opioid receptors, monoaminergic receptors, muscarinic receptors and voltage sensitive Ca ion channels. Unlike other general anaesthetic agents, ketamine does not interact with GABA receptors.
Ketamine is indicated as an anesthetic agent for recommended diagnostic and surgical procedures. If skeletal muscle relaxation is needed, it should be combined with a muscle relaxant. If the surgical procedure involves visceral pain, it should be supplemented with an agent that obtunds visceral pain. Ketamine can be used for induction of anesthesia prior other general anesthetic agents and as a supplement of low potency agents. Reports have indicated a potential use of ketamine as a therapeutic tool for the management of depression when administered in lower doses. These reports have increased the interest for ketamine in this area and several clinical trials are launched for this indication.
