Drug Class and Mechanism
Crestor is an oral drug for lowering blood cholesterol levels. It belongs to a class of drugs, called HMG-CoA reductase inhibitors, more commonly referred to as "statins". Other drugs in this class include simvastatin (Zocor), lovastatin (Mevacor), pravastatin (Pravachol), atorvastatin (Lipitor) and fluvastatin (Lescol). These drugs reduce cholesterol levels by inhibiting HMG-CoA reductase, an enzyme that produces cholesterol in the liver. Crestor and other statins lower blood total cholesterol as well as blood LDL cholesterol levels. LDL cholesterol is the "bad" type of cholesterol that increases the risk of coronary artery disease (atherosclerosis) and heart attacks. Lowering LDL cholesterol levels slows the progression of coronary artery disease and may even reverse it. Statins also increase HDL cholesterol, the "good" type of cholesterol, and reduce triglycerides.
