III期临床试验
筛选例,入选例。
随机分为三组:
第一组(对照组):isoniazid,rifampin,pyrazinamide,andethambutolfor8weeks,然后,isoniazidandrifampin18周;
第二组:isoniazid,rifampin,pyrazinamide,andmoxifloxacinfor17weeks,然后,9周空白对照;
第三组:moxifloxacin,rifampin,pyrazinamide,andethambutolfor17weeks,然后,9周空白对照。
观察治疗失败或复发率。
结论:
两个包含莫西沙星的治疗方案比对照组有更快速的细菌学阴转率,而且疗程缩短至4个月,也没显示出更劣的治疗效果。
