发表在《JAMA Intern Med》的一项由美国、加拿大、英国等国科学家进行的随机临床试验,考察了吸烟者中伐尼克兰、安非他酮和尼古丁贴片治疗的心血管安全性。

重点:药物治疗可以提高戒烟成功率,但是大家对此类药物心血管安全性的担心越来越多。

目的:比较不同药物戒烟疗法的相对心血管安全性风险。

设计、地点和参与者:在140个多国医疗中心进行一项双盲、随机、三模拟、安慰剂和主动对照试验(评估全球戒烟研究中的不良事件[EAGLES])及其非治疗延期试验。纳入8058位吸烟者,至少接受一种戒烟药物治疗,有/无确定的精神病学诊断。以及一个完成12周治疗+12周随访,同意额外28周随访的4595人亚组。

干预:伐尼克兰1mg每天2次;安非他酮150mg每天2次;和尼古丁替代疗法,贴片21mg/d。

主要结局和测量指标:首要终点是进展为主要心血管事件的时间(MACE:心血管死亡、非致命性心肌梗死或非致命中风);次要终点是MACE和其他相关心血管事件的发生(MACE+:MACE或新发或需要介入治疗的恶化的外周血管疾病、冠状动脉血管重建或因不稳定型心绞痛住院)。

结果:在8058名参与者中,3553例(44.1%)为男性(平均[SD]年龄,46.5[12.3]岁)。治疗和随访期间心血管事件发生率较低(MACE<0.5%,MACE+<0.8%),不同疗法差异不显着。发生心血管事件的时间、血压或心率无显着的治疗差异。与安慰剂相比,接受伐尼克兰或安非他酮治疗的患者到MACE发作的时间无显着差异(伐尼克兰:风险比:0.29;95% CI,0.05~1.68;安非他酮:风险比:0.5;95% CI,0.10~2.50)。

结论和相关性:无证据表明使用戒烟药物治疗会增加治疗期间或治疗后严重心血管不良事件的风险。EAGLES及其延期试验的结果提供了进一步的证据,即戒烟药物不会增加一般吸烟者的严重心血管事件风险。

Cochrane :戒烟治疗安全有效

  一篇综述性文章证实:流行的戒烟药物,如尼古丁替代品和抗抑郁药,可提高戒烟率且无太大安全风险。   来自英国牛津大学Cochrane烟草成瘾组织高级研究员,该研究的领导人Kate Cahill 说:"看起来戒烟药物的作用很明显。这些虽不是灵丹妙药,但如果你打算尝试的话,通常确实可提高你戒烟的可能性。而且这些药物使用安全。"   Cahill带领研究小组从发表在考克兰协助网
