Overview
11 DESCRIPTION Rosuvastatin is a 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA)-reductase inhibitor. The chemical name for 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 with the following structural formula: The empirical formula for rosuvastatin calcium is (C 22 H 27 FN 3 O 6...
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Rosuvastatin is an inhibitor of HMG-CoA reductase, the rate-limiting enzyme that converts 3‑hydroxy‑3‑methylglutaryl coenzyme A to mevalonate, a precursor of cholesterol. 12.2 Pharmacodynamics Inhibition of HMG-CoA reductase by rosuvastatin accelerates the expression of LDL-receptors, followed by the uptake of LDL-C from blood to the liver, leading to a decrease in plasma LDL-C and total cholesterol. Sustained inhibition of cholesterol synthesis in the liver also decreases levels of very-low-density lipoproteins. The maximum LDL-C reduction of rosuvastatin is usually achieved by 4 weeks and is maintained after that. 12.
Indications
- 1 INDICATIONS AND USAGE Rosuvastatin tablets is indicated: To reduce the risk major adverse cardiovascular (CV) events (CV death, nonfatal myocardial infarction, nonfatal stroke, or an arterial revascularization procedure) in adults without established coronary heart disease who are at increased risk of CV disease based on age, high-sensitivity C-reactive protein (hsCRP) ≥2 mg/L, and at least one additional CV risk factor. As an adjunct to diet to: Reduce low-density lipoprotein cholesterol (LDL-C) in adults with primary hyperlipidemia.

Interactions
- 7 DRUG INTERACTIONS See full prescribing information for details regarding concomitant use of rosuvastatin with other drugs that increase the risk of myopathy and rhabdomyolysis. ( 7.1 ) Aluminum and Magnesium Hydroxide Combination Antacids : Administer rosuvastatin at least 2 hours before the antacid. ( 7.2 ) Warfarin : Obtain INR prior to starting rosuvastatin.
