Cholestyramine

Common brand names:

Questran

Cholestyramine is bile acid sequestrant—a class of drugs that binds bile acids, prevents their reabsorption from the digestive system, and reduces cholesterol levels. Cholestyramine is one of many drugs used to lower cholesterol levels in people with high cholesterol.

Bile acids are produced in the liver from cholesterol and secreted into the small intestine to help with the absorption of dietary fat and cholesterol. Bile acid sequestrants bind bile acids in the small intestine and carry them out of the body. This causes the body to use more cholesterol to make more bile acids, which are secreted into the small intestine, bound to bile acid sequestrants, and carried out of the body. The end result is lower cholesterol levels. Bile acid sequestrants also prevent absorption of some dietary cholesterol.
