AP&T: 二甲双胍在慢性肝病患者中的安全性和药代动力学

2020-02-16 不详 MedSci原创

FDA批准的二甲双胍有肝功能不全导致乳酸性酸中毒的风险,因此,本项研究旨在探究二甲双胍在慢性肝病(CLD)患者中的安全性和药代动力学影响。

背景及目的
FDA批准的二甲双胍有肝功能不全导致乳酸性酸中毒的风险,因此,本项研究旨在探究二甲双胍在慢性肝病(CLD)患者中的安全性和药代动力学影响。

方法
通过对已经开始服用二甲双胍(n = 34)的患者进行横断面调查,并通过一项前瞻性研究对二甲双胍(500mg,每天两次)进行前瞻性研究,研究对象为有或无2型糖尿病(T2DM)的慢性肝病患者。试验时间长达6周(n = 24)。监测血浆二甲双胍和乳酸浓度。从没有CLD的健康人群和T2DM人群中获得了单独的药代动力学并将其与先前发表的值进行了比较。

结果
所有血浆二甲双胍和乳酸浓度均保持在假定的安全阈值以下(二甲双胍为5 mg / L;乳酸为5 mmol / L)。乳酸浓度与稳态二甲双胍平均浓度无关。在患有CLD的患者中,T2DM与血浆乳酸浓度更高(比不使用T2DM的患者高48%,P<0.0001)。患有肝硬化的CLD患者的乳酸浓度比没有肝硬化的CLD患者高23%(P= 0.01)。二甲双胍在CLD患者中的药代动力学与T2DM无肝病的患者相似。表观二甲双胍清除率(CLMet/ F)与健康受试者相比,CLD患者的肌酐清除率略低(中位数,四分位数范围; 12.6、9.5-15.9与14.9、13.4-16.4;P= 0.03)。

结论
在CLD患者中,二甲双胍的药代动力学变化不大,不足以引起对二甲双胍不安全浓度的担忧。在接受二甲双胍的CLD患者中未观察到不安全的血浆乳酸浓度
