Clin Pharmacokinet:唾液可作为血浆中伏立康唑监测的替代物

2015-04-26 范伟译 MedSci原创

背景和目的:伏立康唑治疗药物的监测(TDM)在临床实践中逐渐的实现。然而,血液采样在儿科和紧急救护病人身上是很困难的,非侵入性技术对治疗药物监测是急需的。本研究的目的是将唾液中伏立康唑的药物动力学与血浆中未释放的和总伏立康唑药物动力学进行比较,以验证唾液作为伏立康唑血浆治疗药物监测的替代物。方法: 在这个药代动力学研究中,配对的血浆和唾液样品取自成人血液病和肺病以伏立康唑治疗的患者。未释放和释放的

背景和目的:伏立康唑治疗药物的监测(TDM)在临床实践中逐渐的实现。然而,血液采样在儿科和紧急救护病人身上是很困难的,非侵入性技术对治疗药物监测是急需的。本研究的目的是将唾液中伏立康唑的药物动力学与血浆中未释放的和总伏立康唑药物动力学进行比较,以验证唾液作为伏立康唑血浆治疗药物监测的替代物。

方法: 在这个药代动力学研究中,配对的血浆和唾液样品取自成人血液病和肺病以伏立康唑治疗的患者。未释放和释放的血浆中伏立康唑浓度采用高通量平衡透析进行分离。伏立康唑浓度采用液相色谱一串联质谱法进行测定。药代动力学参数采用对数线性回归进行计算。

结果: 六十三对来自10例(7个血液病和3个肺病)患者的样品。唾液vs血浆中未释放和总伏立康唑浓度皮尔森相关系数(R值)显示出很强的相关性,值分别为0.970(p < 0.001)和0.891(p < 0.001)。线性混合模型显示唾液中伏立康唑浓度和血浆未释放的伏立康唑浓度之间呈较强的一致性,平均偏差为-0.03(95%置信区间-0.14到0.09;p = 0.60)。总浓度低于10 mg / L,唾液对血浆总伏立康唑浓度的平均比率为0.51±0.08(n = 63)。

结论: 唾液可作为血浆伏立康唑治疗药物监测的可靠替代物,它可以很容易地在临床实践中得以实现。
