Abstract
The objective was to evaluate the in vitro and in vivo phosphate binding properties of cross-linked chitosan iron (III) (CH-Fe(III)-CL), a potential oral phosphate binder for treating hyperphosphatemia. At equilibrium, the in vitro phosphate binding of CH-Fe(III)-CL was 23.6 mg g(-1) for simulated gastrointestinal conditions. In hyperphosphatemic rats, CH-Fe(III)-CL was similar to iron sulfate in reducing serum phosphate by about 35%.
