TITLE: | |
摘要: | 目的:建立同时测定人血浆中卡马西平、文拉法辛、罗格列酮和硝苯地平浓度的方法。方法:血浆样品经甲醇(含0.1%甲酸)沉淀蛋白后,以盐酸吡格列酮为内标,采用超高效液相色谱-串联质谱法测定。色谱柱为Waters ACQUITY UPLC HSS C18,流动相为含0.01%甲酸的水溶液-含0.01%甲酸的甲醇溶液(梯度洗脱),流速为0.3 mL/min,柱温为50 ℃,进样量为5 μL;采用电喷雾离子源,以多反应监测模式进行正离子扫描,用于定量分析的离子对分别为m/z 237.00→194.05(卡马西平)、m/z 278.20→58.10(文拉法辛)、m/z 358.08→135.04(罗格列酮)、m/z 347.15→315.17(硝苯地平)、m/z 357.09→134.06(内标)。结果:卡马西平、盐酸文拉法辛、盐酸罗格列酮、硝苯地平血药浓度的线性范围分别为2.00~2 000.00、2.12~2 120.00、2.00~2 000.00、2.04~1 020.00 ng/mL(r分别为0.995 9、0.990 5、0.991 5、0.991 0,n=5),最低检测限分别为0.200、0.106、0.100、1.020 ng/mL;日内、日间RSD均小于15%,相对误差的绝对值小于15%;提取回收率为65.66%~96.36%(RSD<15%,n=5),基质效应为80.99%~114.33%。采用该法测得2例癫痫患者体内卡马西平的血药浓度分别为(1 500.41±169.11)、(1 159.01±59.24)ng/mL(RSD分别为11.27%、5.60%,n=3),2例高血压患者体内硝苯地平的血药浓度分别为(14.68±1.92)、(21.18±3.59)ng/mL(RSD分别为16.98%、13.10%,n=3)。结论:该方法操作简便,专属性强,灵敏度、准确度高,可用于上述药物的血药浓度监测及药动学研究。 |
ABSTRACT: | OBJECTIVE: To develop a method for simultaneous determination of carbamazepine, venlafaxine, rosiglitazone and nifedipine in human plasma. METHODS: UPLC-MS/MS method was adopted to determine plasma sample after precipitated with methanol (containing 0.1% formic acid) using pioglitazone hydrochloride as internal standard. The determination was performed on Waters ACQUITY UPLC HSS C18 column with mobile phase consisted of aqueous solution containing 0.01% formic acid-methanol containing 0.01% formic acid (gradient elution) at the flow rate of 0.3 mL/min. The column temperature was 50 ℃, and sample size was 5 μL. ESI was used for positive ion scanning by multi reaction monitoring mode. The ion pairs for quantitative analysis were m/z 237.00 to 194.05 (carbamazepine), m/z 278.20 to 58.10 (venlafaxine), m/z 358.08 to 135.04 (rosiglitazone), m/z 347.15 to 315.17 (nifedipine), m/z 357.09 to 134.06 (internal standard). RESULTS: The liner ranges of carbamazepine, venlafaxine hydrochloride, rosiglitazone hydrochloride and nifedipine were 2.00-2 000.00 (r=0.995 9,n=5), 2.12-2 120.00(r=0.990 5, n=5), 2.00-2 000.00(r=0.991 5, n=5) and 2.04-1 020.00(r=0.991 0,n=5) ng/mL; the minimum detection limits were 0.200, 0.106, 0.100, 1.020 ng/mL, respectively. RSDs of inter-day and intra-day were less than 15%. The absolute values of RE were less than 15%. The extraction recoveries were 65.66%-96.36%(RSD%<15%,n=5), and matrix effects ranged 80.99%-114.33%. The plasma concentrations of carbamazepine in 2 epileptic patients were (1 500.41±169.11), (1 159.01±59.24) ng/mL(RSD were 11.27%, 5.60%,n=3). The plasma concentrations of nifedipine in 2 hypertensive patients were (14.68±1.92),(21.18±3.59)ng/mL(RSD were 16.98%, 13.10%,n=3). CONCLUSIONS: The method is simple, specific, sensitive, accurate and suitable for the monitoring of plasma concentration and pharmacodynamic study of above drugs. |
