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 is1H-Pyrrole-1-heptanoic acid, 2-(4-fluorophenyl)- β, δ-dihydroxy-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)carbonyl]-calcium salt (2:1), trihydrate [R-(R*,R*)]-. The empirical formula of atorvastatin calcium is C 66 H 68 CaF 2 N 4 O 10 .3H 2 O and its molecular weight is 1209.42. Its structural formula is: Atorvastatin calcium is a white to off-white crystalline powder that is insoluble in aqueous solutions of pH 4.5 and below.
