Gallamine triethiodide
Gallamine triethiodide (CAS: 65-29-2), with the molecular formula C30H60I3N3O3 and a molecular weight of 891.53 g/mol, is a non-depolarizing neuromuscular blocking agent. It functions as a competitive antagonist at the nicotinic acetylcholine receptor. Primarily recognised for its historical use in anaesthesia to induce skeletal muscle relaxation, it is now more commonly employed as a research tool in pharmacology and physiology studies investigating cholinergic systems.

Neuromuscular Blockade Research
Gallamine triethiodide is used in pharmacological research to study the mechanisms of neuromuscular transmission and to investigate the function of nicotinic acetylcholine receptors.
Physiological Studies
It serves as a valuable tool in physiological research to understand cholinergic signaling pathways and their effects on muscle function and neuronal activity.
Antagonist in Receptor Studies
As a selective antagonist, it is employed to block acetylcholine's action at neuromuscular junctions, allowing researchers to isolate and study other neurotransmitter systems or receptor subtypes.
