Medchemexpress LLC Sevelamer carbonate | 845273-93-0 | MFCD18904375 | 5 G

Sevelamer carbonate is an orally active, non-calcium-based phosphate binding agent used in research for hyperphosphatemia of chronic kidney disease (CKD). It effectively lowers serum phosphorus levels with minimal impact on serum calcium or chloride levels in vivo. It is considered an improved, buffered form of sevelamer, with carbonate replacing chloride as the anion.

Lowers serum phosphorus levels
May cause less metabolic acidosis
Effective in attenuating chronic hyperphosphatemia in animal models
