Pharmaceutical compositions for and methods of treating an animal, including a human, and methods of preparing such compositions. The pharmaceutical compositions contain crosslinked amine polymers and may be used, for example, to treat diseases or other metabolic conditions in which removal of protons and/or chloride ions from the gastrointestinal tract would provide physiological benefits such as normalizing serum bicarbonate concentrations and the blood pH in an animal, including a human. |

1. A pharmaceutical composition comprising a proton-binding, crosslinked amine polymer comprising the residue of an amine corresponding to Formula 1:wherein R1, R2 and R3 are independently hydrogen, hydrocarbyl, substituted hydrocarbyl provided, however, at least one of R1, R2 and R3 is other than hydrogen, the crosslinked amine polymer has an equilibrium swelling ratio in deionized water of about 5 or less, and the crosslinked amine polymer binds a molar ratio of chloride ions to interfering ions of at least 0.35:1, respectively, in an interfering ion buffer at 37° C. wherein (i) the interfering ions are phosphate ions and the interfering ion buffer is a buffered solution at pH 5.5 of 36 mM chloride and 20 mM phosphate or (ii) the interfering ions are phosphate, citrate and taurocholate ions (combined amount) and the interfering ion buffer is a buffered solution at pH 6.2 including 36 mM chloride, 7 mM phosphate, 1.5 mM citrate, and 5 mM taurocholate. |
