利福昔明片治疗急性感染性腹泻的多中心临床研究

目的:观察利福昔明片治疗急性感染性腹泻的临床疗效和安全性.方法:采用多中心随机双盲双模拟平行对照方法,以环丙沙星片作为对照.253例急性感染性腹泻患者被随机分成试验组(127例)和对照组(126例).试验组给利福昔明片,d1为0.4g,po,tid,d2起改为0.4g,bid.对照组给环丙沙星片,d1为0.5g,po,tid,d2起改为0.5g,bid.疗程3～7d.结果:试验组和对照组疗效分别为90.40%和93.55%;无显著性差异(P>0.05).试验组发生不良反应1例1次,发生率为0.79%;对照组5例7次,发生率为3.79% (其中1例因不良事件导致脱落).结论:利福昔明片是治疗急性感染性腹泻有效且安全的口服制剂,不良反应发生率低于环丙沙星片.
