背景 金雀花碱(一种以高亲和力与α4β2 烟碱性乙酰胆碱受体结合的部分激动剂)是一种有可能对辅助戒烟有效的低花费治疗。本研究评估了金雀花碱与安慰剂相比的疗效与安全性。 方法 我们进行了一项单中心、随机、双盲、安慰剂对照的试验。参与者被随机分为两组,一组接受金雀花碱治疗 25 天,另一组接受匹配的安慰剂治疗 25天。研究期间,两组参与者均接 受最小量的咨询。主要转归衡量指标是治疗结束后持续性、经生化(检查)证实的戒烟 12 个月。在被筛查的 1542 名成年吸烟者中,740名被纳入(研究),并且 370名被随机分入每个研究组。 结果 金雀花碱组(吸烟者)持续 12个月戒烟率为 8.4%(31 名参与者),相比之下安慰剂组为 2.4%(9 名参与者)[差 异 为 6.0%,95%可 信 区 间(CI)2.7-9.2戒烟的花费,P=0.001]。在 12 个月随访时的 7 天点戒烟率在金雀花碱组为 13.2%,对安慰剂组的 7.3%(P=0.01)。胃肠不良事件在金雀花碱组报告更频繁(差异为5.7%,95%CI 1.2~10.2)。 结论 在这项单中心研究中,金雀花碱用于戒烟比安慰剂更有效。与用于戒烟的其他药物治疗相比戒烟的花费,金雀花碱较低的价格有可能使其成为一项花费可以承受的治疗,以推进全球戒烟。 :, a that binds with high to the α(4)β(2) , is a low-cost that may be in .
