Colesevelam is a medication primarily used to lower cholesterol levels in the blood. It belongs to a class of drugs known as bile acid sequestrants, which work by binding to bile acids in the intestine. This process helps to reduce the amount of cholesterol absorbed from food and encourages the liver to use more cholesterol to produce bile acids, ultimately lowering overall cholesterol levels. In addition to its cholesterol-lowering effects, colesevelam is also approved for managing blood sugar levels in adults with type 2 diabetes. It can be used alongside other diabetes medications to improve glycemic control. Patients should consult their healthcare provider for proper usage and potential side effects.
