  The present invention relates to method of treating a gastrointestinal motility disorder in a subject in need of treatment comprising coadministering to said subject a first amount of a compound having 5-HT 3 receptor agonist activity or a pharmaceutically acceptable salt, hydrate or solvate thereof; and a second amount of at least one gastric acid suppressing agent (e.g., a proton pump inhibitor, an H 2 receptor antagonist or a pharmaceutically acceptable salt, hydrate or solvate thereof; or an acid pump antagonist or pharmaceutically acceptable salt, hydrate or solvate thereof) wherein the first and second amounts together comprise a therapeutically effective amount. In particular, the method is for treating GERD, including nocturnal GERD. The invention further relates to a method of treating nocturnal GERD comprising administering to a subject in need thereof a therapeutically effective amount of a compound having 5-HT 3 receptor agonist activity or a pharmaceutically acceptable salt, hydrate or solvate thereof. The invention further relates to a method of increasing esophageal motility in a subject in need thereof. The method of increasing esophageal motility can be achieved by administration of a compound having 5-HT 3 receptor agonist activity or a pharmaceutically acceptable salt, hydrate or solvate thereof. The coadministration can also be used to increase esophageal motility.

  本发明涉及治疗需要治疗的受试者胃肠道运动紊乱的方法，包括向所述受试者联合施用第一种量的具有 5-HT 3 受体激动剂活性的化合物或其药学上可接受的盐、水合物或溶液；以及第二种量的至少一种胃酸抑制剂（如质子泵抑制剂、H 2 受体拮抗剂或其药学上可接受的盐、水合物或溶液；或酸泵拮抗剂或其药学上可接受的盐、水合物或溶液），其中第一和第二量共同构成治疗有效量。特别是，该方法用于治疗胃食管反流病，包括夜间胃食管反流病。本发明进一步涉及一种治疗夜间胃食管反流病的方法，该方法包括向有需要的受试者施用治疗有效量的具有 5-HT 3 受体激动剂活性的化合物或其药学上可接受的盐、水合物或溶液。本发明进一步涉及一种增加需要者食管蠕动的方法。增加食管蠕动的方法可通过给予具有 5-HT 3 受体激动剂活性的化合物或其药学上可接受的盐、水合物或溶液。联合给药也可用于增加食管运动。
