ABSTRACT

Molsidomine, coronary drug which acts similar to organic nitrates, belongs to the drug class of sydnones . SIN-1A metabolite of Molsidomine has pharmacologically active group of NO, which by increasing levels of cGMP, decreases levels of intracellular calcium ions in smooth muscle cells. This effect leads to relaxation of smooth muscle vasculature, inhibits platelets aggregation and has indirect antiproliferative effect. In clinical observations no effect of tolerance to the drug was observed. Experimental data show additional mechanism of action of the drug: SIN-1C metabolites protects the reoxygenated cardiomyocyte from post-reperfusion damage. Indications for use of Molsidomine are: ischaemic heart disease, chronic heart failure and pulmonary hypertension. Effects of Molsidomine use in acute myocardial infarction and unstable angina were compared in clinical trials to effects of nitroglycerin use. Both drugs were found equally potent, but authors underline the fact of better Molsidomine tolerability comparing NTG, but longer serum half-time of Molsidomin effects that control of the treatment is worse. In clinical trials it was suggested that intravenous use of Molsidomine metabolite SIN-1 during PTCA procedures is more effective than use of isosorbide dinitrate in the same procedures. In other clinical trials molsidomin was found to produce beneficial effects in patients with heart failure due to ischaemic cardiomyopathy, dilatative cardiomyopathy, in essential hypertension, pulmonary artery hypertension in COPD patients and in congestive heart failure.
