simvastatin - Generic Medications

Simvastatin is a prodrug of 3-hydoroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor that is derived synthetically from a fermentation product of Aspergillus terreus. 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-[1α,3α,7β,8β(2S * ,4S * ),-8aβ]]. The molecular formula of simvastatin is C 25 H 38 O 5 and its molecular weight is 418.57. Its structural formula is: Simvastatin, USP is a white to off-white, nonhygroscopic, crystalline powder that is practically insoluble in water, and freely soluble in chloroform, methanol and ethanol. Simvastatin tablets, USP for oral use contain 5 mg, 10 mg, 20 mg, 40 mg or 80 mg of simvastatin, USP and the following inactive ingredients: ascorbic acid, citric acid monohydrate, hydroxypropyl cellulose, hypromellose, iron oxide yellow (5 mg), lactose monohydrate, magnesium stearate, microcrystalline cellulose, pregelatinized maize starch, talc, and titanium dioxide. Butylated hydroxyanisole is added as a preservative. simvastatin-structure.jpg

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 β-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-4­hydroxy-6-oxo-2H-pyran-2-yl)-ethyl]-1-naphthalenyl ester, [1S-[1α,3α,7β,8β(2S*,4S*),-8aβ]]. The empirical formula of simvastatin is C 25 H 38 O 5 and its molecular weight is 418.57. Its structural formula is: Simvastatin is a white to off-white, nonhygroscopic, crystalline powder that is practically insoluble in water, and freely soluble in chloroform, methanol and ethanol. Simvastatin tablets, USP for oral administration contain either 5 mg, 10 mg, 20 mg, 40 mg or 80 mg of simvastatin and the following inactive ingredients: ascorbic acid, citric acid, hypromellose, iron oxides, lactose, magnesium stearate, povidone, microcrystalline cellulose, pregelatinized starch (maize), talc,colloidal silicone dioxide and titanium dioxide. Butylated hydroxyanisole is added as a preservative. Simvastatin 10mg, 20mg, and 40 mg contain red and yellow ferric oxide. Simvastatin 80 mg contains red ferric oxide. Structure
