Why is Atorvastatin Prescribed?

Atorvastatin 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 those who have heart disease or who are at risk of developing heart disease. Atorvastatin is also used to decrease 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.

How Does Atorvastatin Work?

Atorvastatin is in 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 atorvastatin has been shown to prevent heart disease, angina (chest pain), strokes, and heart attacks.
