英国警示氢氯噻嗪非黑色素瘤皮肤癌风险

2019-02-03 MedSci MedSci原创

英国药品和健康产品管理局(MHRA)2018年11月14日发布消息,警示含氢氯噻嗪类产品长期使用存在累积的剂量依赖性的非黑色素瘤皮肤癌风险,建议服用该类产品的患者定期检查和报告任何可疑的皮肤损害或痣,限制阳光和紫外线照射暴露时间,并采取防晒措施。含氢氯噻嗪的药品主要用于治疗高血压,以及与心脏病、肝病或慢性心功能不全(心力衰竭)相关的水肿。在英国,氢氯噻嗪仅与其他药物固定剂量组合使用,估计约有28,

英国药品和健康产品管理局(MHRA)2018年11月14日发布消息,警示含氢氯噻嗪类产品长期使用存在累积的剂量依赖性的非黑色素瘤皮肤癌风险,建议服用该类产品的患者定期检查和报告任何可疑的皮肤损害或痣,限制阳光和紫外线照射暴露时间,并采取防晒措施。

含氢氯噻嗪的药品主要用于治疗高血压,以及与心脏病、肝病或慢性心功能不全(心力衰竭)相关的水肿。在英国,氢氯噻嗪仅与其他药物固定剂量组合使用,估计约有28,000名患者服用含有氢氯噻嗪的药品。

最近两项丹麦全国数据来源(包括丹麦癌症登记库和国家处方登记库)的药物流行病学研究结果显示,氢氯噻嗪和非黑色素瘤皮肤癌之间存在累积的剂量依赖关系。氢氯噻嗪的已知光敏作用可能是该风险的作用机制。基于总体情况或累计使用分析,研究者没有发现基底细胞癌或鳞状细胞癌(包括鳞状细胞唇癌)风险与其他利尿剂和降压药存在类似相关性,这些药品包括苄氟噻嗪、钙通道阻滞剂、血管紧张素转换酶抑制剂、血管紧张素II受体拮抗剂和呋塞米。Pedersen等的研究结果显示,基于因果推断,研究期间诊断出的9/100鳞状细胞癌病例和小于1/100基底细胞癌病例可能与氢氯噻嗪的使用有关。Pottegrd等研究结果显示,研究期间发生的病例中,11/100鳞状细胞唇癌可能与氢氯噻嗪的使用有关。

所有含氢氯噻嗪制剂的产品特征概要和患者使用说明书已更新,纳入并提示非黑色素瘤皮肤癌的风险,有关风险和建议的信函也已发给处方医生和分发该类药品的药剂师。

给医务人员的建议:

  • 药物流行病学研究表明,随着氢氯噻嗪累积剂量增加,剂量依赖性非黑色素瘤皮肤癌(基底细胞癌和鳞状细胞癌,包括鳞状细胞唇癌)风险增加。
  • 告知正在服用含氢氯噻嗪药品的患者,氢氯噻嗪可能与非黑色素瘤皮肤癌相关,特别是在长期使用时,建议患者定期检查和报告新出现或已变化的皮肤损害或痣。
  • 建议既往有皮肤癌的患者重新考虑是否使用氢氯噻嗪。
  • 检查所有可疑的皮肤损害或痣(包括皮肤组织活检的病理检查)。
  • 建议患者限制日光和紫外线暴露时间,并采取恰当的防晒措施,从而减少皮肤癌风险。
