gallamine triethiodide gallamine triethiodide gallamine triethiodide (flaxedil) 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 is a non-depolarising type of blocker as it binds to the acetylcholine receptor but does not have the biological activity of acetyl choline. gallamine triethiodide has a parasympatholytic effect on the cardiac vagus nerve, which causes tachycardia and occasionally hypertension. very high doses cause histamine release. presence of iodine makes it radio opaque, and its ampule in a bag at airport's x-ray scanner raise the false suspicion of a bullet in the bag. gallamine triethiodideclinical datatrade namesflaxedilahfs/drugs.cominternational drug namesatc codem03ac02 (who) identifiers iupac name 2,2’,2’’-tris(n,n,n-triethylethanaminium) triiodide cas number65-29-2 ypubchem cid6172iuphar/bps356drugbankdb00483 ychemspider5937 nuniiq3254x40x2keggd02292 ychebichebi:503442 ychemblchembl1200993 nchemical and physical dataformulac30h60n3o3+3 · 3 i− (gallamine triethiodide)c24h45n3o3 (gallamine)molar mass891.529 g/mol (gallamine triethiodide)423.633 g/mol (gallamine)3d model (jsmol)interactive image smiles ...o(c1c(occ(cc)(cc)cc)cccc1occ(cc)(cc)cc)cc(cc)(cc)cc inchi inchi=1s/c24h45n3o3/c1-7-25(8-2)16-19-28-22-14-13-15-23(29-20-17-26(9-3)10-4)24(22)30-21-18-27(11-5)12-6/h13-15h,7-12,16-21h2,1-6h3 ykey:iclwtjimxvissr-uhfffaoysa-n y ny (what is this?) (verify) an ampoule of gallamine. gallamine triethiodide was commonly used to prevent muscle contractions during surgical procedures, but now superseded by new neuromuscular blocking drugs with less side effects. it was developed by daniel bovet in 1947. the pharmaceutical is no longer marketed in the united states, according to the fda orange book.
