DESCRIPTION Rosuvastatin (Rovista ), a synthetic lipid-lowering agent, is an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. Rosuvastatin calcium is bis[(E)-7-[4-(4-fluorophenyl)-6-isopropyl-2- [methyl(methylsulfonyl)amino] pyrimidin-5-yl](3R,5S)-3,5-dihydroxyhept- 6-enoic acid] calcium salt. The empirical formula for rosuvastatin calcium is (C 22 H 27 FN 3 O 6 S) 2 Ca. Its structural formula is: FORMULATION Rosuvastatin (Rovista ) is available for oral administration as: 1. Rosuvastatin (Rovista ) Tablets 5mg Each film-coated tablet contains: Rosuvastatin…5mg (as calcium salt) 2. Rosuvastatin (Rovista ) Tablets 10mg Each film-coated tablet contains: Rosuvastatin…10mg (as calcium salt) 3. Rosuvastatin (Rovista ) Tablets 20mg Each film-coated tablet contains: Rosuvastatin…20mg (as calcium salt) CLINICAL PHARMACOLOGY MECHANISM OF ACTION Rosuvastatin is a selective and competitive inhibitor of HMG-CoA reductase, the rate-limiting enzyme that converts 3-hydroxy-3-methylglutaryl coenzyme A to mevalonate, a precursor for cholesterol. The primary site of action of rosuvastatin is the liver, the target organ for cholesterol lowering. In _in vivo_ and _in vitro_ studies, rosuvastatin produces its 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 of VLDL and LDL particles. PHARMACOKINETICS _Absorption_ Maximum plasma concentration is achieved approximately in 5 hours after oral administration. The absolute bioavailability is approximately 20%. Both peak concentration (C max ) and area under the plasma concentration-time curve (AUC) increased in approximate proportion to rosuvastatin dose. Administration of rosuvastatin with food decreased the rate of drug absorption by 20% as assessed by C max , but there was no effect on the extent of absorption as assessed by AUC. _Distribution_ Rosuvastatin is taken up Aqra d-dokument sħiħ
