EMA委员会:双氯芬酸的风险与COX-2抑制剂类似

2013-06-20 佚名 丁香园

欧洲药品管理局(EMA)药物警戒风险评估委员会(PRAC)已经完成对双氯芬酸的审查,认为这款药物能造成与选择性COX-2抑制剂相类似的风险,特别是在使用高剂量(150mg) 或长期使用时风险更明显。然而,药物警戒风险评估委员会表示双氯芬酸受益超过其风险,医生应该像给患者使用选择性COX-2抑制剂时一样,采取相同的措施以减少血栓栓塞事件。 根据药物警戒风险评估委员会提供的信息,“患有严重

欧洲药品管理局(EMA)药物警戒风险评估委员会(PRAC)已经完成对双氯芬酸的审查,认为这款药物能造成与选择性COX-2抑制剂相类似的风险,特别是在使用高剂量(150mg) 或长期使用时风险更明显。然而,药物警戒风险评估委员会表示双氯芬酸受益超过其风险,医生应该像给患者使用选择性COX-2抑制剂时一样,采取相同的措施以减少血栓栓塞事件。

根据药物警戒风险评估委员会提供的信息,“患有严重潜在心脏或循环系统症状,如心力衰竭、心脏疾病、循环系统疾病或先前患有心脏病发作或中风的患者不应使用双氯芬酸,存有某些心血管危险因素的患者(如高血压、血液中胆固醇升高、糖尿病或吸烟)应该在经过仔细考虑后才能使用双氯芬酸。也建议医疗保健专业人员定期评估患者是否需要继续使用双氯芬酸。”

2012年10月,药物警戒风险评估委员会在欧洲药品管理局针对发布的非甾体类抗炎药物(NSAIDs)心血管安全评价信息完成了一项报告之后,发起了对双氯芬酸的这次审查。像药物警戒风险评估委员会一样,欧洲药品管理局认为,与其它非甾体类抗炎药物相比,使用双氯芬酸时心血管副作用会出现持续但很小的增长,并且这种风险与使用COX-2抑制剂所观察到的风险基本一致。

当前药物警戒风险评估委员会的结论基于所有已经发布和未发布的数据。这些建议将马上被转到相互认可和分散程序协调小组,这是一个代表欧盟成员国的组织,它将给出最终意见。

EMA committee concludes diclofenac poses similar risks as COX-2 inhibitors
London, UK - The Pharmacovigilance Risk Assessment Committee (PRAC) of the European Medicines Agency (EMA) has completed its review of diclofenac and concluded that the drug poses similar risks as selective COX-2 inhibitors, particularly when used in high doses (150 mg) or when used long term [1].
Still, committee says the benefits of diclofenac exceed the risks and that physicians should take the same precautions to minimize thromboembolic events as they do with patients treated with selective COX-2 inhibitors....

研究者呼吁双氯芬酸应从全球退市

  研究人员正呼吁广泛应用的疼痛药物双氯芬酸从全球市场退市,因该产品存在较高的心脏病发作风险及其它心血管不良事件。双氯芬酸是一种非甾体抗炎药物(NSAID),该药物通常被用来缓解疼痛以及关节炎引起的炎症。   但研究人员说该药物也伴有几乎与万络(Vioxx)相同的严重心血管方面的副作用,目前该产品有多种品牌名,其中包括扶他林(Voltaren)。   当初,万络被大加吹捧可以大大提
