Zocor, also known as Simvastatin, used to lower levels of cholesterol and other fats in the blood. Zocor belongs to the group of medicines called 3-Hydroxy-3-Methylglutaryl Coenzyme A (HMG-CoA) Reductase Inhibitors. They work by blocking an enzyme that is needed to make cholesterol.

ZOCOR (simvastatin) is a lipid-lowering agent that is derived synthetically from a fermentation product of Aspergillus terreus. After oral ingestion, simvastatin, which is an inactive lactone, is hydrolyzed to the corresponding b-hydroxyacid form. This is an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. This enzyme catalyzes the conversion of HMG-CoA to mevalonate, which is an early and rate-limiting step in the biosynthesis of cholesterol. Simvastatin is butanoic acid, 2,2-dimethyl-,1,2,3,7,8,8a- hexahydro-3,7-dimethyl-8-[2-(tetrahydro-4-hydroxy-6-oxo- 2H-pyran-2-yl)-ethyl]-1-naphthalenyl ester, [1S-[1a,3a,7b,8b(2S*,4S*),-8ab]]. The empirical formula of simvastatin is C25H38O5 and its molecular weight is 418.57. Tablets ZOCOR for oral administration contain either 5 mg, 10 mg, 20 mg, 40 mg or 80 mg of simvastatin and the following inactive ingredients: cellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose, iron oxides, lactose, magnesium stearate, starch, talc, titanium dioxide and other ingredients. Butylated hydroxyanisole is added as a preservative.
