Atorvastatin works by blocking an enzyme in the liver that your body uses to make cholesterol. When less cholesterol is produced, the liver takes up more cholesterol from the

Lipitor - Atorvastatin 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.
