Description_x000D_ General description_x000D_ Rosuvastatin calcium (ROS) has a molecular mass of 1001.14. ROS is a member of the "statins" group and is a 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor._x000D_ Application_x000D_ Rosuvastatin calcium has been used to determine the effect of the treatment with SIM, rosuvastatin or PRA on cholesterol and HMGCR levels in HeLa cells and to evaluate the in vivo effects of statins on glucose homeostasis._x000D_ Packaging_x000D_ 10, 50 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ Rosuvastatin calcium is a competitive inhibitor of hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase, the enzyme that catalyzes the conversion of HMG-CoA to mevalonic acid, the rate-limiting step in cholesterol biosynthesis. Rosuvastatin calcium is antilipemic and is used to reduce plasma cholesterol levels and prevent cardiovascular disease.
