Gallamine Triethiodide is used as a neuromuscular blocking agent, paralyzing locally during anesthetization.
일반 설명
Gallamine triethiodide,[v-phenenyl-tris(oxyethylene)]tris[triethylammonium] triiodide(Flaxedil), is a skeletal muscle relaxant that works byblocking neuromuscular transmission in a manner similar tothat of d-tubocurarine (i.e., a nondepolarizing blockingagent). It does have some differences, however. It has astrong vagolytic effect and a persistent decrease in neuromuscularfunction after successive doses that cannot be overcome by cholinesterase inhibitors. Gallamine triethiodidealso has muscarinic antagonistic properties and bindswith greater affinity to the M2 receptors than to the M1 receptor.This latter characteristic may cause its strongvagolytic action.
Clinical Use
Gallamine Triethiodide is contraindicated in patients with myastheniagravis, and one should remember that its action is cumulative,as with curare. The antidote for gallamine triethiodideis neostigmine.
Safety Profile
Poison by ingestion, subcutaneous, intravenous, parenteral, intraduodenal, intraperitoneal, and intramuscular routes. Whenheated to decomposition it emits very toxic fumes of NH3, NOx, and Ií.
