The invention describes novel nitrosated and/or nitrosylated H
2
receptor antagonist compounds, and novel compositions comprising at least one H
2
receptor antagonist compound that is optionally substituted with at least one NO and/or NO
2
group, and, optionally, at least one compound that donates, transfers or releases nitric oxide, stimulates endogenous synthesis of nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor or is a substrate for nitric oxide synthase and/or at least one nonsteroidal antiinflammatory drug, antacid, bismuth-containing reagent or anti-viral agent. The invention also describes methods for treating and/or preventing gastrointestinal disorders; improving gastroprotective properties of H
2
receptor antagonists; decreasing the recurrence of ulcers; facilitating ulcer healing; preventing and/or treating inflammations and microbial infections, ophthalmic diseases and disorders, multiple sclerosis, and viral infections; and decreasing or reducing the gastrointestinal toxicity associated with the use of nonsteroidal antiinflammatory compounds.
本发明描述了新型的硝酸化和/或亚硝酸化H2受体拮抗剂化合物,以及至少包含一种H2受体拮抗剂化合物的新型组合物,该化合物可选择性地取代至少一个NO和/或NO2基团,并且可选择地包含至少一种捐赠、转移或释放一氧化氮、刺激内源性一氧化氮合成、提高内源性内皮源性舒张因子水平或是一氧化氮合酶底物和/或至少一种非甾体抗炎药、抗酸剂、含铋试剂或抗病毒药物。本发明还描述了治疗和/或预防胃肠道疾病的方法;改善H2受体拮抗剂的胃保护性能;减少溃疡复发;促进溃疡愈合;预防和/或治疗炎症和微生物感染、眼科疾病和疾病、多发性硬化症和病毒感染;并减少或降低与非甾体抗炎化合物使用相关的胃肠道毒性。
