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. Atorvastatin calcium is [R-(R*,R*)]-2-(4-fluorophenyl)-ß,δ-dihydroxy-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic acid, calcium salt (2:1).The empirical formula of atorvastatin calcium is C 66 H 68 Ca F 2 N 4 O 10 and its molecular weight is 1155.36. Its structural formula is: Atorvastatin calcium is a white to off-white colored powder free from visible extraneous matter. Atorvastatin calcium is soluble in dimethyl sulphoxide, slightly soluble in alcohol, very slightly soluble in water, in pH 7.4 phosphate buffer and in acetonitrile and practically insoluble in aqueous solutions of pH 4 and below. Atorvastatin calcium tablets for oral administration contain 10, 20, 40, or 80 mg atorvastatin and the following inactive ingredients: anhydrous lactose, NF; colloidal silicon dioxide, NF; copovidone, NF; croscarmellose sodium, NF; magnesium stearate, NF; mannitol, USP; silicified microcrystalline cellulose, NF; sodium bicarbonate, USP; sodium carbonate anhydrous, NF; sodium lauryl sulfate, NF; lecitihin, polyvinyl alcohol part hydrolyzed, talc, titanium dioxide, xanthan gum and iron oxide yellow.
