在12周的时间里,米拉贝格伦和维贝格伦在老年女性治疗过度活动膀 (OAB) 的有效性和安全性相似. 这种初始药物治疗的比较为选择一线β3-上腺素受体激动剂提供了初步见解.
科学领域:
- 老年医学 老年医学
- 药理学 药理学是指药理学的学科.
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
背景情况:
- 过度活跃的膀 (OAB) 显著影响老年妇女的生活质量.
- 药物治疗是管理OAB症状的基石.
研究的目的:
- 为了比较mirabegron和vibegron的疗效和安全性,作为老年妇女过度活动膀 (OAB) 的初始药物治疗.
- 评估OAB症状评分 (OABSS) 和其他相关患者报告结果的变化.
主要方法:
- 一项前性,随机化,开放性试验涉及131名70岁以上的绝经后妇女,她们患有OAB.
- 参与者在12周内每天接受一次50毫克的mirabegron或50毫克的vibegron.
- 主要终点是OABSS从基线到第12周的变化;次要终点包括IPSS,KHQ,MCIC和安全结果.
主要成果:
- 米拉贝格朗和维贝格朗都在OAB症状中显示出显著的小组内改善.
- 在两种药物之间的初级终点 (OABSS变化) 中没有观察到统计学上显著的差异.
- 与治疗相关的不良事件是可比的,通常是轻微的,群体之间的发生率没有显著差异.
结论:
- 作为老年女性OAB的初始治疗方法,Mirabegron和vibegron的疗效和安全性表现相似.
- 这些发现为选择一线β3上腺体受体激动剂提供了初步指导.
- 由于研究的单中心设计和有限的统计能力,需要进行更大的多中心试验来证实这些结果.
