Published: July 26, 2026Updated: August 25, 2026

Gallamine is a non-depolarizing neuromuscular blocking agent historically used as an adjunct to general anesthesia during surgical procedures. It works by competitively blocking acetylcholine receptors at the neuromuscular junction, causing temporary muscle relaxation.

Used to produce skeletal muscle relaxation during surgical procedures, particularly abdominal surgeries and procedures requiring endotracheal intubation. Also used as an adjunct in electroconvulsive therapy and mechanical ventilation.

Acts as a competitive antagonist at nicotinic acetylcholine receptors at the neuromuscular junction. By blocking acetylcholine binding, it prevents depolarization of the motor end plate, resulting in muscle paralysis. Has additional vagolytic properties that may cause increased heart rate.

Should only be administered by trained personnel familiar with neuromuscular blocking agents. Requires adequate ventilation and airway support. Contraindicated in patients with myasthenia gravis. Use with caution in patients with impaired renal function as it is primarily excreted unchanged by the kidneys. Has been largely replaced by newer neuromuscular blocking agents with more favorable safety profiles.
