What is atorvastatin?

• Atorvastatin is an HMG CoA reductase inhibitor. Atorvastatin blocks the production of cholesterol (a type of fat) in the body.
• Atorvastatin is used to reduce the amounts of LDL (bad) cholesterol, total cholesterol, triglycerides (another type of fat), and apolipoprotein B (a protein needed to make cholesterol) in your blood. Atorvastatin is also used to increase the level of HDL (good) cholesterol in your blood. These actions are important in reducing the risk of hardening of the arteries, which can lead to heart attacks, stroke, and peripheral vascular disease.
• Atorvastatin may also be used for purposes other than those listed in this medication guide.
