Drug NameLipitor (Atorvastatin) Drug UsesLipitor is used with diet changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol and certain fatty substances in your blood. Accumulation of cholesterol and fats along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to your heart, brain, and other parts of your body. Lowering your blood level of cholesterol and fats may help to prevent heart disease, angina (Chest pain), strokes, and heart attacks. How to useLipitor comes as a tablet to take it orally. It is usually taken once a day with or without food. To help you remember to take Lipitor, take it around the same time every day. Your doctor may start you on a low dose of Lipitor and gradually increase your dose. Continue to take Lipitor even if you feel well. Do not stop taking Lipitor without talking to your doctor. Eat a low-cholesterol, low-fat diet Drug Class and MechanismAtorvastatin is an oral drug that lowers the level of cholesterol in the blood. It belongs to a class of drugs referred to as statins which includes lovastatin (Mevacor), simvastatin, (Zocor), fluvastatin (Lescol), and pravastatin (Pravachol). All statins, including atorvastatin, prevent the production of cholesterol by the liver by blocking the enzyme that makes cholesterol, HMGCoA reductase. They lower total blood cholesterol as well as LDL cholesterol levels. (LDL cholesterol is believed to be the "bad" cholesterol that is primarily responsible for the development of coronary artery disease.) Lowering LDL cholesterol levels retards progression and may even reverse coronary artery disease. Unlike the other drugs in this class, atorvastatin also can reduce the concentration of triglycerides in the blood. High blood concentrations of triglycerides also have been associated with coronary artery disease. Atorvastatin was approved by the FDA in December of 1996.

What is atorvastatin?
Atorvastatin is a cholesterol-lowering medication that blocks the production of cholesterol (a type of fat) in the body.
Atorvastatin reduces low-density lipoprotein (LDL) cholesterol and total cholesterol in the blood. Lowering your cholesterol can help prevent heart disease and hardening of the arteries, conditions that can lead to heart attack, stroke, and vascular disease.
Atorvastatin is used to treat high cholesterol. Atorvastatin is also used to lower the risk of stroke, heart attack, or other heart complications in people with coronary heart disease or type 2 diabetes.
Atorvastatin may also be used for other purposes not listed in this medication guide.
