The effect of olsalazine on stool output and the transit of a solid radiolabelled meal through the stomach, small intestine and colon was studied in six patients with ulcerative colitis intolerant of sulphasalazine. Olsalazine 250 mg four times daily significantly accelerated gastric emptying (mean +/- SD; 45.3 +/- 24.2 min v 67.3 +/- 33.1 min, p less than 0.05), mouth to caecum transit time (242 +/- 41 min v 325 +/- 33 min, p less than 0.02) and whole gut transit time (60.5 +/- 26 h v 37.8 +/- 17.8 h, p less than 0.05). No significant changes were seen in mean daily stool weight (215 +/- 41 g v 162 +/- 62 g) and mean daily stool frequency (2.2 +/- 0.6 v 2.4 +/- 1.8). None of these patients developed diarrhoea, but acceleration of gastric and intestinal transit may be responsible for the diarrhoea reported in some patients taking this drug.
在6例对柳氮磺胺吡啶不耐受的溃疡性结肠炎患者中,研究了奥沙拉嗪对粪便排出量以及固体放射性标记餐通过胃、小肠和结肠的转运的影响。奥沙拉嗪每日4次,每次250mg,显著加快了胃排空(平均值±标准差;45.3±24.2分钟对67.3±33.1分钟,p<0.05)、口腔至盲肠转运时间(242±41分钟对325±33分钟,p<0.02)和全肠道转运时间(60.5±26小时对37.8±17.8小时,p<0.05)。平均每日粪便重量(215±41g对162±62g)和平均每日排便频率(2.2±0.6对2.4±1.8)未见显著变化。这些患者均未出现腹泻,但胃和肠道转运加快可能是一些服用该药物的患者报告出现腹泻的原因。
