Gallamine is a medication used during surgeries to relax skeletal muscle and reduce muscle contractions. Synonyms for gallamine include flaxedil, gallamex, and gallamin. Additionally, it is known as gallamine triethiodide. It is an anticholinergic drug that acts by blocking the action of acetylcholine at the postganglionic parasympathetic nerve endings, leading to relaxation of the skeletal muscles. Other similar medications that act on the neuromuscular junction include atracurium, cisatracurium, vecuronium, and rocuronium. When used in combination with anesthesia, they are referred to as neuromuscular blocking agents, and they are critical in facilitating surgical procedures by allowing for easier access to the affected areas.
