Mechanism Of Action Cholestyramine forms a resin that acts as a bile acid sequestrant to limit the reabsorption of bile acids in the gastrointestinal tract. Cholestyramine resin is a strong anion exchange resin, allowing it to exchange its chloride anions with anionic bile acids present in the gastrointestinal tract and form a strong resin matrix. Cholestyramine consists of a functional group, which is a quaternary ammonium group attached to an inert styrene-divinylbenzene copolymer, in the anion exchange resin.
Description of the Drug: Cholestyramine is a bile acid sequestrant used as an adjunct in the reduction of elevated serum cholesterol in patients with primary hypercholesterolemia, and for the relief of pruritus associated with partial biliary obstruction.
