The active ingredient in sevelamer carbonate tablets is sevelamer carbonate, a polymeric amine that binds phosphate and is meant for oral administration. It was developed as a pharmaceutical alternative to sevelamer hydrochloride. Sevelamer carbonate is an anion exchange resin with the same polymeric structure as sevelamer hydrochloride in which carbonate replaces chloride as the counterion. While the counterions differ for the two salts, the polymer itself, the active moiety involved in phosphate binding, is the same. Sevelamer carbonate tablets are known chemically as poly (allylamine-co-N,N'-diallyl-1,3-diamino-2-hydroxypropane) carbonate salt. Sevelamer carbonate is hygroscopic, but insoluble in water.

Chemical Structure of Sevelamer Carbonate Sevelamer carbonate tablets: Each film-coated tablet of sevelamer carbonate tablets contains 800 mg of sevelamer carbonate on an anhydrous basis. The inactive ingredients are carnauba wax, hypromellose, hydroxypropyl cellulose, microcrystalline cellulose, polyethylene glycol, sodium chloride, titanium dioxide, and zinc stearate. The tablet imprint contains black iron oxide, propylene glycol and hypromellose. Sevelamer Carbonate Chemical Structure
