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 allylamine polymer with 1-chloro-2,3-epoxypropane, [6-(allylamino)-hexyl]trimethylammonium chloride and N-allyldecylamine, 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 citrus-flavored, a white to yellow granular powder containing yellow granules packaged in single-dose packets containing 3.75 gram colesevelam hydrochloride. In addition, each packet contains the following inactive ingredients: microcrystalline cellulose, medium chain triglycerides, simethicone emulsion, colloidal silicon dioxide, propylene glycol alginate, magnesium trisilicate, lemon-lime flavor, orange flavor, citric acid monohydrate, and aspartame (<5 calories per 3.75 gram single-dose packet).PHENYLKETONURICS: colesevelam hydrochloride for oral suspension contains 33.6 mg phenylalanine per 3.75 gram dose. colese-struc
