calcium carbimide calcium carbimide calcium carbimide, sold as the citrate salt under the trade name temposil, is a disulfiram-like medication. its effects are similar to the medication disulfiram (antabuse) in that it interferes with the normal metabolism of alcohol by preventing the breakdown of the metabolic byproduct acetaldehyde. the result is that when alcohol is consumed by users of calcium carbimide, they experience severe reactions which include symptoms such as sweating, difficulty breathing, rapid heartbeat, rash, nausea and vomiting, and headache. calcium carbimideclinical dataahfs/drugs.cominternational drug namesatc coden07bb02 (who) identifiers iupac name calcium 2-hydroxypropane-1,2,3-tricarboxylate; methylcyanamide cas number156-62-7 ycitrated: 8013-88-5 ypubchem cid6335910chemspider21106422 yuniizlr270912wcitrated: 21zcd2aa4h ychemblchembl2106095 nchemical and physical dataformulac6h6o7.c2h4n2.ca3d model (jsmol)interactive image smiles .o=c()cc(o)(cc(=o)o)c()=o.n#cnc inchi inchi=1s/c6h8o7.c2h4n2.ca/c7-3(8)1-6(13,5(11)12)2-4(9)10;1-4-2-3;/h13h,1-2h2,(h,7,8)(h,9,10)(h,11,12);4h,1h3;/q;;+2/p-2 ykey:zzobqlacmmnmct-uhfffaoysa-l y ny (what is this?)
