Atorvastatin calcium tablets are 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. Atorvastatin calcium is (3 R ,5 R )-7-[2-(4-fluorophenyl)-3-phenyl-4-(phenylcarbamoyl)-5-(propan-2-yl)-1 H -pyrrol-1-yl]-3,5-dihydroxyheptanoate calcium trihydrate. Its structural formula is: C 66 H 68 CaF 2 N 4 O 10 •3H 2 O M.W. 1209.42 Atorvastatin calcium trihydrate (Form I) is a white to off-white powder that is insoluble in aqueous solutions of pH 4.5 and below. Atorvastatin calcium is very slightly soluble in distilled water, pH 7.8 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 of atorvastatin and the following inactive ingredients: calcium carbonate, croscarmellose sodium, hydroxypropyl cellulose, hypromellose, lactose monohydrate, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polysorbate, talc and titanium dioxide.
