Ketazolam Products | Cleanchem - Ketamine hydrochloride is a dissociative anesthetic used for anesthesia induction and maintenance, as well as for pain management. It works by blocking NMDA receptors in the brain, leading to analgesia, sedation, and altered perception. More recently, ketamine has been investigated and approved in some regions for treatment-resistant depression and suicidal ideation at sub-anesthetic doses. It has potential for abuse due to its dissociative and hallucinogenic effects.
