The present disclosure is directed to a pharmaceutical composition comprising a compound of formula (X), in combination with another active agent, and to the use of said composition in methods for the treatment of disorders associated with fluid retention or salt overload or gastrointestinal tract disorders, such as irritable bowel syndrome and constipation associated with cystic fibrosis. The methods generally comprise administering to a mammal in need thereof 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 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.
本公开涉及一种药物组合物,该组合物包含与另一种活性剂组合的式(X)化合物,并涉及将所述组合物用于治疗与体液潴留或盐超载相关的疾病或胃肠道疾病(如肠易激综合征和与囊性纤维化相关的便秘)的方法。这些方法一般包括向有需要的哺乳动物施用包含此类化合物的药物组合物,该组合物设计为在胃肠道(GI)中基本活跃,以抑制其中钠离子和氢离子的 NHE 介导的反转运。更具体地说,该方法包括向有需要的哺乳动物施用包含这种化合物的药物组合物,该化合物可抑制胃肠道中NHE-3、-2和/或-8介导的钠离子和/或氢离子的反转运,并且设计成基本上不渗透到上皮细胞层,或更具体地说,不渗透到胃肠道上皮细胞层。由于该化合物基本上不渗透,因此不会被吸收,从而基本上不会被全身生物利用,从而限制了其他内脏器官(如肝脏、心脏、大脑等)对该化合物的接触。
