Abstract

Olsalazine (azodisalicylate) is a new drug in which two molecules of 5-aminosalicylic acid are linked by an azo bond. Its role in the treatment of mildly active, distal ulcerative colitis was investigated. Sixty patients were randomly allocated to receive olsalazine 1 g or a placebo as a retention enema nightly for two weeks. Clinical improvement was seen in 19 (66%) and sigmoidoscopic improvement in 17 (59%) of the 29 patients receiving olsalazine compared with 12 (43%) and 11 (39%), respectively, of the 28 in the control group. These differences were not significant. In a second trial 40 patients were randomised to receive oral olsalazine 2 g daily or a placebo capsule for two weeks. Significant clinical and sigmoidoscopic improvement was seen in the patients receiving oral olsalazine compared with the patients receiving placebo capsules. Oral olsalazine may be valuable in the treatment of mildly active ulcerative colitis. Its role in maintaining remission is yet to be determined.

摘要

奥沙拉嗪(偶氮二水杨酸)是一种新药,其中两分子的5-氨基水杨酸通过一个偶氮键相连。对其在治疗轻度活动性远端溃疡性结肠炎中的作用进行了研究。60名患者被随机分配,每晚接受1克奥沙拉嗪或安慰剂保留灌肠,为期两周。接受奥沙拉嗪治疗的29名患者中,19名(66%)有临床改善,17名(59%)有乙状结肠镜检查改善,而对照组的28名患者中分别为12名(43%)和11名(39%)。这些差异不显著。在第二项试验中,40名患者被随机分配,每天口服2克奥沙拉嗪或服用安慰剂胶囊,为期两周。与接受安慰剂胶囊的患者相比,接受口服奥沙拉嗪的患者有显著的临床和乙状结肠镜检查改善。口服奥沙拉嗪在治疗轻度活动性溃疡性结肠炎中可能有价值。其在维持缓解中的作用尚待确定。
