Atorvastatin calcium is a synthetic lipid-lowering agent. Atorvastatin is an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. This enzyme catalyzes the conversion of HMG-CoA to mevalonate, an early and rate-limiting step in cholesterol biosynthesis. The drug substance used in atorvastatin calcium tablets is atorvastatin calcium in the form of propylene glycol solvate. The chemical name for atorvastatin calcium propylene glycol solvate is calcium bis((3R,5R)-7-[3-(anilinocarbonyl)-5-(4-fluorophenyl)-2-isopropyl-4-phenyl-1H-pyrrol-1-yl]-3,5-dihydroxyheptanoate) propylene glycol solvate. The empirical formula of atorvastatin calcium propylene glycol solvate is C 66 H 68 CaF 2 N 4 O 10 * C 3 H 8 O 2 and its molecular weight is 1231.46. Its structural formula is: Atorvastatin calcium is a white to off-white solid that is insoluble in aqueous solutions of pH 4 and below. Atorvastatin calcium is slightly soluble in distilled water, pH 7.4 phosphate buffer, and acetonitrile; slightly soluble in ethanol; and freely soluble in methanol. Atorvastatin calcium tablets for oral administration contain 10, 20, 40, or 80 mg atorvastatin and the following inactive ingredients: calcium acetate, croscarmellose sodium, sodium carbonate, microcrystalline cellulose, magnesium stearate (vegetable source), colloidal silicon dioxide, hypromellose, hydroxypropyl cellulose, polyethylene glycol and titanium dioxide. chemical-structure
