Atorvastatin is a statin medicine that lowers cholesterol. Doctors prescribe it to reduce the risk of heart attack and stroke, especially in people with heart disease or diabetes.
What Is Atorvastatin Used For?
- High LDL (“bad”) cholesterol
- High triglycerides
- Lowering the risk of heart attack and stroke
- Inherited high cholesterol (familial hypercholesterolemia)
How Does Atorvastatin Work?
Atorvastatin blocks an enzyme called HMG-CoA reductase, which your liver uses to make cholesterol. Your liver then makes less cholesterol and removes more LDL from your blood.
