中文摘要: 目的:建立测定人血浆中伏立康唑浓度的方法。方法:血浆经乙腈沉淀蛋白后,以利鲁唑为内标,采用高效液相色谱(HPLC)法测定其中伏立康唑的血药浓度。色谱柱为AgilentZorbaxEclipsePlusC18,流动相为乙腈-0.01mol/L磷酸二氢钾溶液(38∶62,V/V),流速为1.0mL/min,柱温为40℃,检测波长为255nm,进样量为20μL。同时将该方法应用于10例使用伏立康唑患者的血药浓度测定。结果:伏立康唑检测质量浓度的线性范围为0.2~20.0μg/mL(r=0.9996),定量下限为0.2μg/mL,日内、日间RSD均小于7%(n=6或n=18),准确度平均值为98.59%~106.18%,提取回收率平均值为86.77%~89.86%(RSD<4%,n=6),稳定性试验实测结果与理论值的偏差在±15%内。10例患者伏立康唑的血药浓度为0.34~5.04μg/mL。结论:本研究成功建立了快速、高效测定人血浆中伏立康唑浓度的HPLC法。
英文摘要: OBJECTIVE:To establis h the method for the determination of voriconazole concentration in human plasma. METHODS:After protein precipitation with acetonitrile ,using riluzole as internal standard ,plasma concentration of voriconazole were determined by HPLC method. The determination was performed on Agilent Zorbax Eclipse Plus C 18 column with mobile phase consisted of acetonitrile- 0.01 mol/L monopotassium phosphate solution (38∶62,V/V)at the flow rate of 1.0 mL/min. The column temperature was maintained at 40 ℃,and the detection wavelength was 255 nm. The sample size was 20 μL. Meanwhile,the method was applied to determine plasma concentration of voriconazole in 10 patients receiving voriconazole. RESULTS :The liner range of voriconazole was 0.2-20.0 μg/mL(r=0.999 6). The lower limit of quantitation was 0.2 μg/mL. RSDs of intra-day and inter-day were both lower than 7%(n=6 or n=18). Average accuracies were 98.59%-106.18%. Average extraction recoveries were 86.77%-89.86%(RSD<4%,n=6),and the deviations of measured results and theoretical values of stability tests were within ±15%. The plasma concentrations of voriconazole in 10 patients were 0.34-5.04 μg/mL. CONCLUSIONS:The study successfully establish a rapid and efficient HPLC method for the determination of voriconazole in human plasma.
