The active ingredient in Welchol is colesevelam hydrochloride, which is a bile acid sequestrant. Bile acid sequestrants work by binding bile acids in the intestine, prompting the liver to use more cholesterol to make new bile acids, thereby lowering cholesterol levels. This mechanism provides a non-systemic way to reduce cholesterol, which can be valuable for those who need alternatives to statins.
