The active ingredient in sevelamer carbonate for oral suspension 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 is known chemically as poly(allylamine- co -N,N’-diallyl-1,3-diamino-2-hydroxypropane) carbonate salt. Sevelamer carbonate is hygroscopic, but insoluble in water. The structure is represented in Figure 1. Sevelamer Carbonate Powder: Each pouch of Sevelamer Carbonate Powder contains 0.8 g or 2.4 g of sevelamer carbonate on an anhydrous basis. The inactive ingredients are ferric oxide (yellow), orange flavor, sucralose and xanthan gum. Chemical Structure
