MedKoo CAT#: 317964

CAS#: 65-29-2

Description: Gallamine Triethiodide is a mAChR M2 antagonist with pronounced cardioselectivity. It acts by combining with the cholinergic receptor sites in muscle and competitively blocks the transmitter action of acetylcholine. It is a synthetic non-depolarizing blocking drug. The actions of gallamine triethiodide are similar to those of tubocurarine but this agent blocks the cardiac vagus and may cause sinus tachycardia and, occasionally, hypertension and increased cardiac output.
