Cholesterol absorption inhibitors for high cholesterol
|Generic Name||Brand Name|
|ezetimibe and simvastatin||Vytorin|
How It Works
Why It Is Used
Cholesterol absorption inhibitors are used to treat high cholesterol. This medicine lowers total cholesterol and LDL (bad) cholesterol.
This medicine is used along with lifestyle changes including diet and exercise to lower cholesterol. It can be used alone or taken with a statin or other cholesterol-lowering medicines. One medicine, Vytorin, is a combination of a cholesterol absorption inhibitor and a statin.
How Well It Works
Ezetimibe (Zetia) lowers total cholesterol and LDL cholesterol levels in people with high cholesterol.
A drug that combines ezetimibe and simvastatin (Vytorin) lowers total cholesterol and LDL levels. But a recent study showed that taking Vytorin may not limit hardening of the arteries (atherosclerosis) any better than the statin medicine alone, based on one way to measure atherosclerosis. But the combination of ezetimibe and simvastatin can lower LDL levels more than simvastatin alone.1 If you are taking Vytorin, or you are taking Zetia and a statin as separate pills, you may want to talk to your doctor before your next refill about switching to simvastatin alone. Because you can buy a generic version of simvastatin or other statin medicines, taking the statin alone can save you money.
Side effects of cholesterol absorption inhibitors may include:
- Stomach ache.

What To Think About
If you have liver disease, do not take a cholesterol absorption inhibitor with a statin.
If you also take bile acid sequestrants (cholestyramine, colestipol, and colesevelam) for high cholesterol, do not take them at the same time as a cholesterol absorption inhibitor. Instead, take your cholesterol absorption inhibitor either 2 hours before or 4 hours after the bile acid sequestrant.
If you also take a statin, you can take a cholesterol absorption inhibitor at the same time as the statin.
