Gallamine

Gallamine (as gallamine triethiodide) is a non-depolarising muscle relaxant. It acts by combining with the cholinergic receptor sites in muscle and competitively blocking the transmitter action of acetylcholine. Gallamine has a parasympatholytic effect on the cardiac vagus nerve which causes tachycardia and occasionally hypertension. Very high doses cause histamine release.

Gallamine is commonly used to stabilize muscle contractions during surgical procedures.
