Colestipol is available as sachets of granules which work in the body as a bile acid sequestrant. This means that it binds to bile acids in your digestive system. It prevents the bile acids from being recycled (reabsorbed) into your body. This action can be useful for people who have higher than normal levels of lipids in their blood.
