    摘要: The present disclosure is directed to compounds and methods for the treatment of disorders associated with fluid retention or salt overload, such as heart failure (in particular, congestive heart failure), chronic kidney disease, end-stage renal disease, liver disease, and peroxisome proliferator-activated receptor (PPAR) gamma agonist-induced fluid retention. The present disclosure is also directed to compounds and methods for the treatment of hypertension. The present disclosure is also directed to compounds and methods for the treatment of gastrointestinal tract disorders, including the treatment or reduction of pain associated with gastrointestinal tract disorders. The methods generally comprise administering to a mammal in need thereof a pharmaceutically effective amount of a compound, or a pharmaceutical composition comprising such a compound, that is designed to be substantially active in the gastrointestinal (GI) tract to inhibit NHE-mediated antiport of sodium ions and hydrogen ions therein. More particularly, the method comprises administering to a mammal in need thereof a pharmaceutically effective amount of a compound, or a pharmaceutical composition comprising such a compound, that inhibits NHE-3, -2 and/or -8 mediated antiport of sodium and/or hydrogen ions in the GI tract and is designed to be substantially impermeable to the layer of epithelial cells, or more specifically the epithelium of the GI tract. As a result of the compound being substantially impermeable, it is not absorbed and is thus essentially systemically non-bioavailable, so as to limit the exposure of other internal organs (e.g., liver, heart, brain, etc.) thereto. The present disclosure is still further directed to a method wherein a mammal is administered such a compound with a fluid-absorbing polymer, such that the combination acts as described above and further provides the ability to sequester fluid and/or salt present in the GI tract.

    摘要: The present invention relates to methods for lowering serum phosphate in a mammal comprising administering an epithelial phosphate transport inhibitor, such as an NHE3 inhibitor, in combination with a phosphate binder as well as pharmaceutical compositions comprising such epithelial phosphate transport inhibitors and phosphate binders.
