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

p-phenylenediamine derivatives as potassium channel regulators and preparation methods and medical application thereof. A compound represented by general formula A or a pharmaceutically acceptable salt thereof. A preparation method of the compound and a use of the same as a potassium channel opener.

The present invention relates to the use of potassium-binding agents that are formulated to remove toxins, e.g., potassium ions, from the gastrointestinal tract at an elevated rate, without causing undesirable side effects, in hemodialysis patients. The compositions exhibit desired characteristics for the long term administration to treat or prevent the relapse or occurrence of certain conditions, for example hyperkalemia.
