Lipitor is used together with diet, weight loss, and exercise to reduce the
risk of heart attack and stroke and to decrease the chance that heart surgery
will be needed in people who have heart disease or who are at risk of
developing heart disease.

Lipitor is also used to lower the amount of fatty substances such as low-
density lipoprotein (LDL) cholesterol ('bad cholesterol') and triglycerides in
the blood and to increase the amount of high-density lipoprotein (HDL)
cholesterol ('good cholesterol') in the blood.

Lipitor may also be used to decrease the amount of cholesterol and other fatty
substances in the blood in children and teenagers 10 to 17 years of age who
have familial heterozygous hypercholesterolemia (an inherited condition in
which cholesterol cannot be removed from the body normally).

Lipitor (atorvastatin) belongs to a class of medications called HMG-CoA
reductase inhibitors (statins). It works by slowing the production of
cholesterol in the body to decrease the amount of cholesterol that may build
up on the walls of the arteries and block blood flow to the heart, brain, and
other parts of the body.

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 with Lipitor has been shown to
prevent heart disease, angina (chest pain), strokes, and heart attacks.
