Colesevelam hydrochloride is a non-absorbed, polymeric, lipid-lowering and glucose-lowering agent for oral administration. Colesevelam hydrochloride is a high-capacity bile acid-binding molecule. Colesevelam hydrochloride is poly (allylamine hydrochloride) cross-linked with epichlorohydrin and alkylated with 1-bromodecane and (6-bromohexyl)-trimethylammonium bromide. The chemical name (IUPAC) of colesevelam hydrochloride is 1-Hexaminium, N,N,N-trimethyl-6-(2-propenylamino)-, chloride, polymer with (chloromethyl) oxirane, 2-propen-4-amine and N-2-propenyl-1-decanamine, hydrochloride. The chemical structure of colesevelam hydrochloride is represented by the following formula: wherein (a) represents allyl amine monomer units that have not been alkylated by either of the 1-bromodecane or (6-bromohexyl)-trimethylammonium bromide alkylating agents or cross-linked by epichlorohydrin; (b) represents allyl amine units that have undergone cross-linking with epichlorohydrin; (c) represents allyl amine units that have been alkylated with a decyl group; (d) represents allyl amine units that have been alkylated with a (6-trimethylammonium) hexyl group, and m represents a number ≥ 100 to indicate an extended polymer network. A small amount of the amines are dialkylated and are not depicted in the formula above. No regular order of the groups is implied by the structure; cross-linking and alkylation are expected to occur randomly along the polymer chains. A large amount of the amines are protonated. The polymer is depicted in the hydrochloride form; a small amount of the halides are bromide. Colesevelam hydrochloride is hydrophilic and insoluble in water. Colesevelam hydrochloride for oral suspension is a lemon-flavored, off-white to pale yellow powder containing yellow granules packaged in a packet containing 3.75 gram colesevelam hydrochloride. In addition, each packet contains the following inactive ingredients: lemon flavor, magnesium aluminum silicate, maltodextrin, medium-chain triglycerides, propylene glycol alginate, silicon dioxide and sucralose. 10
