Lipitor (Atorvastatin)

Lipitor 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.

Atorvastatin 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.

Do not take Lipitor without first talking to your doctor if you have liver disease. Before taking Lipitor, tell your doctor if you have a chronic muscular disease, require major surgery, or have a blood disorder. You may not be able to take Lipitor, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above. Lipitor is in the FDA pregnancy category X. This means that Lipitor is known to cause birth defects if it is taken during pregnancy.

Contact your doctor immediately if you experience unexplained muscle pain, tenderness, or weakness, especially if accompanied by a fever or flulike symptoms or yellowing of the skin or eyes, abdominal pain, unexplained fatigue, dark colored urine or pale colored stools. These may be early symptoms of muscle or liver problems.
