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 the body remove cholesterol from the bloodstream, leading to improved heart health. In addition to its cholesterol-lowering effects, Colesevelam is also used to help manage blood sugar levels in people with type 2 diabetes. It can be taken as a tablet or in a powder form mixed with water, making it a versatile option for patients.
