Abstract

Polymers and compositions utilizing such polymers are disclosed for treating hyperphosphatemia and other illnesses associated with elevated serum phosphate levels. Phosphate binding polymers, or a pharmaceutically acceptable salt of the polymers, comprise pendent groups extending from a backbone of the polymer. Each pendent group comprises at least two nitrogen-bearing functional groups which bind phosphate. Variations of such polymer and compositions are disclosed.
