Rosuvastatin
Generic name: rosuvastatin
Brand names: Crestor
What is rosuvastatin?
Rosuvastatin (Crestor) is a prescription medicine used to treat high cholesterol and to reduce the risk of major cardiovascular events such as heart attack and stroke.
Rosuvastatin belongs to a class of medicines called statins. It works by blocking HMG-CoA reductase, the rate-limiting enzyme the liver uses to make cholesterol. With cholesterol synthesis reduced, the liver increases its LDL receptors and clears more LDL, or "bad" cholesterol, from the blood. LDL and total cholesterol levels fall, with the maximum reduction usually reached by four weeks.
Rosuvastatin comes as a tablet. It was first approved by the US Food and Drug Administration (FDA) on August 12, 2003, under the brand name Crestor. Many generic versions of rosuvastatin tablets have since been approved.
What is rosuvastatin used for?
Rosuvastatin is used:
