Lancet Respir Med:噻托溴铵用于1-5岁儿童持续性哮喘

2018-01-17 zhangfan MedSci原创

研究证实,噻托溴铵对1-5岁持续性哮喘患儿表现出良好的耐受性和症状缓解效果,其与吸入性激素联用可有效控制哮喘复发

很少有研究对5岁以下儿童哮喘药物的安全性和有效性进行评估。近日研究人员评估了噻托溴铵对1-5岁持续性哮喘儿童的安全性和有效性。

在这项II-III期、12周、随机、双盲、安慰剂及平行对照研究中,11个国家的32个医疗中心参与研究。1-5岁的,至少6个月哮喘史,需接受糖皮质激素吸入治疗的儿童参与研究。患儿随机在激素治疗的基础上,接受每天1次,2.5、5μg的噻托溴铵或安慰剂。研究的主要终点包括安全性,疗效评估为12周每周平均日间哮喘发作变化。

102名患者参与研究,其中2.5 μg噻托溴铵组36人,5μg噻托溴铵组32人,安慰剂组34人。101人完成研究。组间12周日间哮喘发作变化差异不显著:2.5 μg噻托溴铵组与安慰剂组的差异为-0.08,5μg噻托溴铵组与安慰剂组的差异为-0.048。噻托溴铵组治疗的不良事件率较低(2.5 μg噻托溴铵组56%,5μg噻托溴铵组58%,安慰剂组74%)。29%的安慰剂组患者报告哮喘加重,而2.5 μg噻托溴铵组为14%,5μg噻托溴铵组为 6%。安慰剂组3人发生严重不良事件,未发生治疗导致的停药或死亡。

研究证实,噻托溴铵对1-5岁持续性哮喘患儿表现出良好的耐受性和症状缓解效果,其与吸入性激素联用可有效控制哮喘复发。
