Thromb Haemost:你所担心的华法林药物相互作用 小题大做?

2018-05-09 吴星 环球医学

华法林是目前临床上应用最广泛的口服抗凝药之一。由于药物的有效性和出血风险均与国际标准化比值(INR)水平相关,因此华法林患者必须定期进行血液检测以监测该参数。华法林与其他众多药物的相互作用更是增加了治疗的复杂性。临床医生和患者在使用华法林联合其他药物时常常面临复杂的决策,这种情况在老年患者中尤为常见。

华法林是目前临床上应用最广泛的口服抗凝药之一。由于药物的有效性和出血风险均与国际标准化比值(INR)水平相关,因此华法林患者必须定期进行血液检测以监测该参数。华法林与其他众多药物的相互作用更是增加了治疗的复杂性。临床医生和患者在使用华法林联合其他药物时常常面临复杂的决策,这种情况在老年患者中尤为常见。

目前关于华法林药物-药物相互作用的大部分知识来源于病例报告和小规模病例系列,尽管可用于提醒临床医生注意潜在的治疗误区,但也有一些不足之处,并且不足以代表普通人群量化的临床影响。2018年3月,发表在《Thromb Haemost》的一项研究调查了既往报道的华法林和其他药物的相互作用对国际标准化比值(INR)人群水平的影响。

在该项研究中,使用健康促进网络(THIN;一个英国初级医疗数据库),研究人员随访了一个2005~2013年华法林使用者的队列(N=121962人),直到对第一个潜在相互作用药物的合格处方进行评估。

研究人员确定了16个子队列,其中每个研究药物为1个队列,还有1个华法林对照子队列。

使用配对学生t检验,通过比较相互作用的药物初始给药前和初始给药后测量的INR值,评估INR水平的短期变化。研究人员也评估了INR值处于治疗范围外(INR:2~3)的患者比例。

结果显示,咪康唑使用与INR平均增加最高相关(+3.35),其次是胺碘酮(+1.28)、氟康唑(+0.79)、甲硝唑(+0.75)和制霉菌素(+0.65)。减去对照子队列中观察到的天然INR差异后,分别在初始使用咪康唑(53.2%)、胺碘酮(45.5%)、甲硝唑(23.3%)、氟康唑(23.2%)和制霉菌素(17.6%)的患者中观察到INR超过治疗水平(INR>3)。

卡马西平使用与INR平均降低-0.63相关,并且46.2%的卡马西平初始使用患者观察到亚治疗水平(INR<2)。

对于所有其他药物,INR改变为小至中等,其中INR改变的绝对单位为+0.23~+0.55,INR水平超过治疗范围的患者比例<16%。

作者认为,多种研究药物都观察到了临床潜在重要的相互作用。虽然经过证实,但在校正标准INR变异后,多数药物对华法林使用者普通人群的影响都非常小。

尽管如此,我们在华法林联合其他药物时仍然不能掉以轻心,要密切关注药物-药物相互作用。
