What Is Atorvastatin and Why Is It Commonly Prescribed?
Atorvastatin is a medication in a group of drugs called statins. It is commonly prescribed to help lower cholesterol levels and reduce the risk of serious cardiovascular problems such as heart attacks and strokes.
It is sold under the brand name Lipitor and is available in generic form.
How does atorvastatin work?
Atorvastatin works mainly by blocking an enzyme in the liver called HMG-CoA reductase, which plays a role in making cholesterol.
As a result, it can:
- Lower LDL cholesterol (“bad” cholesterol)
- Reduce certain blood fats called triglycerides
- Slightly increase HDL cholesterol (“good” cholesterol) in some people
- Help slow the buildup of fatty plaques in arteries
Why is atorvastatin prescribed?
Doctors commonly prescribe atorvastatin for:
1. High cholesterol
It helps lower cholesterol levels when diet and exercise alone are not enough.
2. Prevention of heart disease
People at increased risk of cardiovascular disease may take atorvastatin to reduce the chance of:
- Heart attack
- Stroke
- Artery-related complications
3. After a heart attack or stroke
Statins are often used to help reduce the risk of future events.
4. Certain high-risk conditions
People with diabetes, high blood pressure, or a strong family history of heart disease may be prescribed a statin depending on their overall risk.
