Ketamine is a dissociative anesthetic widely used in both human and veterinary medicine for its sedative, pain-relieving, and anesthetic properties. Originally approved by the FDA in 1970, it works by blocking N-methyl-D-aspartate (NMDA) receptors in the brain, disrupting the transmission of pain signals and inducing a trance-like state. In addition to its medical applications, ketamine has gained recognition in recent years for its off-label use in treating depression, anxiety, and post-traumatic stress disorder (PTSD), particularly in patients who do not respond to traditional treatments. Administered in controlled, low doses, it can rapidly alleviate symptoms of depression and suicidal ideation, offering a novel approach to mental health care. However, ketamine also has a history of recreational misuse due to its hallucinogenic and dissociative effects, which underscores the importance of careful medical oversight.
