背景:骨质疏松结构的破坏和减少骨形成骨脆性结果,增加骨吸收。在第二阶段的临床试验,一种口服有效的药物,游离骨重塑,增加骨形成,减少骨吸收,雷奈酸锶,已被证明,以减少脊椎骨折的风险,并增加骨密度。方法:防止脊椎骨折在3期临床试验,以评估雷奈酸锶的疗效,我们随机分配1649骨质疏松症的绝经后妇女低骨矿物密度(),并至少有一个脊椎骨折,接受2克或每天口服雷奈酸锶安慰剂3年。我们给两组的钙和维生素D补充剂之前和期间的研究。脊椎X光片获得了每年进行骨密度测量,每半年。结果:新的椎体骨折发生在雷奈酸锶组患者比安慰剂组少,在第一年的治疗和41%的风险减少了49%,在三年的学习期间(相对风险,0.59; 95 %置信区间为0.48至0.73)。雷尼酸锶腰椎14.4%和8.3%,增加骨密度,股骨颈(两种比较,P <0.001),在36个月。有严重不良事件的发生率在组之间没有显着差异。结论:与雷奈酸锶治疗绝经后骨质疏松症导致脊椎骨折的风险,在早期和持续减少。版权所有2004年马萨诸塞州医学会
