25717-80-0CCOC([O-])=Nc1c[n+](N2CCOCC2)no1XLFWDASMENKTKL-UHFFFAOYSA-NMolsidomine is a member of the class of oxadiazoles that is 1,2,3-oxadiazole substituted by morpholin-4-yl and (ethoxycarbonyl)azanidyl groups at positions 3 and 5, respectively. It is used as a vasodilator drug for the treatment of myocardial ischemic syndrome and congestive heart failure. It has a role as an antioxidant, a vasodilator agent, a nitric oxide donor, an apoptosis inhibitor and a cardioprotective agent. It is an ethyl ester, a zwitterion, a member of morpholines and an oxadiazole.

Molsidomine, a cardiovascular drug, acts in a similar fashion to organic nitrates. The SIN-1A metabolite of molsidomine has a pharmacologically active group of nitric oxide, which increases levels of cyclic GMP, and decreases intracellular calcium ions in smooth muscle cells. This leads to relaxation of smooth muscle in the blood vessels, and inhibits platelet aggregation.
Molsidomine hepatically metabolized to _linsidomine_. Linsidomine releases nitric oxide (NO) from endothelial cells when it decays, and acts as the active vasodilating metabolite responsible for molsidomine's pharmacological effects. Oral absorption of Molsidomine is found to be 95.5% ±4.5. Presystemic metabolism is noted to be 56% and metabolism is reported extensive by Liver. Renal Excretion accounts for 95 % and plasma half-life is 5 hr. Back to top
Peak plasma drug concentration (tmax) occurs from 1 to 2 hours after administration.

renal excretion is the main route of elimination of the metabolites in humans (90% to 95%) About 2% of the ingested drug is excreted unchanged in the urine.
