Rosuvastatin calcium is hydrophilic compound with a partition coefficient (octanol/water) of 0. 13 at Ph of 7.0
Clinical Pharmacology
ROSUTOR 10 is a selective and competitive inhibitor of HMG-CoA reductase, the rate-limiting enzyme that converts 3-hydroxyl-3-methyl glutaryl coenzyme-A to mevalonate, a precursor of cholesterol. In vivo studies in an animal, and in vitro studies in cultured animal and human cells have shown rosuvastatin to have a high uptake into, and selectivity for action in the liver, the target organ for cholesterol lowering. In vivo and in vitro studies, rosuvastatin produces it lipid modifying effects in two ways, First, it increases the number of hepatic LDL receptors on the cell- surface to enhance uptake and catabolism of LDL second, rosuvastatin inhibits hepatic synthesis of VLDL, which reduces the total number VLDL and LDL particles.
