Atorvastatin calcium (Lipitor) is a white, round film-coated tablet containing atorvastatin calcium. Atorvastatin calcium is a synthetic lipid-lowering agent, which 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 empirical formula of atorvastatin calcium is (C₃₃H₃₄FN₂O₅)₂Ca·3H₂O and its molecular weight is 1209.42.
Atorvastatin calcium is a white to off-white crystalline powder, practically insoluble in aqueous solutions of pH 4 and below. It is very slightly soluble in distilled water, pH 7.4 phosphate buffer, and acetonitrile; slightly soluble in ethanol; and freely soluble in methanol.
