Ketamine is not classified as a muscle relaxant; instead, it is commonly used as an anesthetic agent. Its primary action is as a dissociative anesthetic, which provides analgesia and sedation by altering the perception of pain and inducing a trance-like state. While it may have some muscle relaxant properties, they are not the primary therapeutic effects when used in clinical practice.

In contrast, succinylcholine, vecuronium, and pancuronium are all neuromuscular blocking agents specifically designed to induce muscle relaxation during surgical procedures or mechanical ventilation. These drugs block the transmission of nerve impulses to the muscles, resulting in paralysis, which is essential for certain surgical interventions where movement needs to be minimized or controlled.

Understanding the distinct roles of these medications is crucial for their appropriate use in anesthesia, highlighting why ketamine stands apart from the muscle relaxants.
