Its mechanism of action is not well understood, but ketamine can block NMDA receptors and may interact with sigma receptors. A cyclohexanone derivative with analgesic and anesthetic properties. Although its mechanism of action is not well understood, ketamine appears exerts complex pharmacological actions including inhibition of biogenic amine uptake, binding to opioid receptors, and inhibition of N-methyl D-aspartate (NMDA) receptors. Because of the involvement of spinal NMDA receptors in the process of central sensitization, this agent may reduce pain perception and induce sedation. A member of the class of cyclohexanones in which one of the hydrogens at position 2 is substituted by a 2-chlorophenyl group, while the other is substituted by a methylamino group. Ketamine induces a trance-like state while providing pain relief, sedation, and memory loss. Other uses include sedation in intensive care and treatment of pain and depression. Heart function, breathing, and airway reflexes generally remain functional. Effects typically begin within five minutes when given by injection, and last up to approximately 25 minutes.
