Suxamethonium chloride (brand names Scoline and Sucostrin, among others), also known as suxamethonium or succinylcholine, or simply sux in medical abbreviation,[5] is a medication used to cause short-term paralysis as part of general anesthesia.[6] This is done to help with tracheal intubation or electroconvulsive therapy.[6] It is administered by injection, either into a vein or into a muscle.[7] When used in a vein, onset of action is generally within one minute and effects last for up to 10 minutes.[7]

Common side effects include low blood pressure, increased saliva production, muscle pain, and rash.[7] Serious side effects include malignant hyperthermia, hyperkalemia and allergic reactions.[8][9] It is not recommended in people who are at risk of high blood potassium or a history of myopathy.[6] Use during pregnancy appears to be safe for the baby.[10]

Suxamethonium is in the neuromuscular blocker family of medications and is of the depolarizing type.[7] It works by blocking the action of acetylcholine on skeletal muscles.[7]

Suxamethonium was described as early as 1906 and came into medical use in 1951.[5] It is on the World Health Organization's List of Essential Medicines.[11] Suxamethonium is available as a generic medication.[7]
