Each film coated tablet contains:
Simvastatin USP 20 mg
MECHANISM OF ACTION
Simvastatin is a prodrug and is hydrolyzed to its active B-hydoxy acid form, simvastatin acid, after administration.simvastatin is a specific inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase, the enzyme that catalyzes the conversion of HMG-CoA to mevalonate,an early and rate limiting step in the biosynthetic pathway for cholesterol. In addition, simvastatin reduces VLDL and TG and increases HDL-C.
SIMSTATIN 10/20/40(Simvastatin Tablets) is an HMG-CoA reductase inhibitor (statin) indicated as an adjunctive therapy to diet to:
-Reduce the risk of total mortality by reducing CHD deaths and reduce the risk of non fatal myocardial infarction, stroke, and the need for revascularization procedures in patients at high risk of coronary events.
-Reduce elevated total-C, LDL-C,Apo B, TG , and increase HDL-C in patients with primary hyperlipidemia(heterozygous familial and nonfamilial) and mixed dyslipidemia.
-Reduce elevate TG in patients with hypertrigiyceridemia and reduce TG and VLDL-C in patient with primary dysbetalipoproteinemia.
-Reduce total-C and LDL-C in adult patients with homozygous familial hypercholesterolemia.
-Reduce elevated total-C, LDL-C,and Apo B in boys and postmenarchal girls,10 to 17years of age with heterozygous familial hypercholesterolemia after failing an adequate trial of diet therapy.
