1/4剂量四药联合疗法可作为高血压初始治疗方案

2017-02-27 PracticeUpdate 爱唯医学网

高血压一直是困扰人类健康的一大难题,但目前普遍采用的单一药物治疗仅能达到平均9/5 mm Hg的降压效果,医师和患者都期待着更为有效的降压策略。近期《Lancet》发表了一篇多种药物联合降压的研究,结果显示,研究者所采用的“四联降压药”降压效果显著。该“四联药”是由1/4剂量的四种降压药物复合而成:厄贝沙坦(37.5 mg)+氨氯地平(1.25 mg)+双氢氯噻嗪(6.25 mg)+阿替洛尔(12

高血压一直是困扰人类健康的一大难题,但目前普遍采用的单一药物治疗仅能达到平均9/5 mm Hg的降压效果,医师和患者都期待着更为有效的降压策略。近期《Lancet》发表了一篇多种药物联合降压的研究,结果显示,研究者所采用的“四联降压药”降压效果显著。



该“四联药”是由1/4剂量的四种降压药物复合而成:厄贝沙坦(37.5 mg)+氨氯地平(1.25 mg)+双氢氯噻嗪(6.25 mg)+阿替洛尔(12.5 mg)。这项多中心、双盲研究是由澳大利亚的四家研究中心联合完成的,参与的患者被随机分配至为期4周的“四联药”降压治疗组(n=18)或安慰剂组(n=18),随后经过2周的洗脱期后进行4周的其它治疗。

患者的基线诊室血压为154/90 mm Hg,动态血压为140/87 mm Hg。经安慰剂校正后,治疗组的24 h动态收缩压下降19 mm Hg(95% CI:14~23),诊室血压下降22/13 mm Hg(P<0.0001)。“四联药”治疗期间,18/18(100%)的患者诊室血压小于140/90 mm Hg,而安慰剂组仅6/18(33%)的患者达到此指标。“四联药”治疗组患者未出现严重不良反应。

通过对既往36个单药1/4剂量试验(n=4721)和6个双药1/2剂量试验(n=312)进行系统性回顾发现,它们的平均降压效果(经安慰剂校正后)为5/2 mm Hg和7/5 mm Hg(二者均P<0.0001)。

本研究结果可谓是高血压治疗领域的一场及时雨,但还需进一步开展大样本量研究并评估该疗法的长期安全性。
