摘 要 目的 建立同时测定癫痫患儿血浆中拉莫三嗪(LTG)、左乙拉西坦(LEV)和吡仑帕奈(PER)浓度的方法并应用于临床。
方法 血浆样品经乙腈沉淀蛋白后,以 PER-D5 为内标,采用超高效液相色谱-串联质谱(UPLC-MS/MS)法检测。色谱柱为
ACQUITY UPLC HSS T3 C18,流动相为含0.1%甲酸的5 mmol/L乙酸铵溶液-乙腈(梯度洗脱),流速为0.3 mL/min,柱温为40 ℃,
进样量为 5 μL,分析时间为 5 min;采用电喷雾离子源,以多反应监测方式进行正离子扫描,用于定量分析的离子对分别为 m/z
255.9→144.9(LTG)、m/z 171.1→126.1(LEV)、m/z 350.1→219.0(PER)、m/z 354.9→220.2(内标)。采用上述 UPLC-MS/MS 法测定
14例联合用药癫痫患儿血浆中上述药物的稳态谷浓度。结果 LTG、LEV、PER检测质量浓度的线性范围分别为0.15~24 μg/mL
(R >0.993)、0.312 5~50 μg/mL(R >0.997)、6.25~1 000 ng/mL(R >0.995),定量下限分别为 0.15 μg/mL、0.312 5 μg/mL、6.25

ng/mL;3种药物日内、日间精密度试验的RSD均不高于9.83%,准确度(相对误差)为-9.33%~13.72%(n=6或n=18);平均提取
回收率为 86.4%~97.9%,平均基质效应为 86.9%~110.0%(n=6);稳定性试验的相对误差绝对值均低于 15%。14 例患儿体内
LTG、LEV、PER 的稳态谷浓度分别为(5.64±4.03)μg/mL、(10.67±8.78)μg/mL、(450.20±251.27)ng/mL,谷浓度达标率分别为
71.4%、37.5%、84.6%。结论 所建UPLC-MS/MS法专属性强、检测速度快,可用于联合用药癫痫患儿的血药浓度监测。

ABSTRACT OBJECTIVE To establish a method for simultaneous determination of plasma concentration of lamotrigine(LTG),
levetiracetam(LEV) and perampanel(PER) in children with epilepsy and apply this method in clinical practice. METHODS Plasma
proteins were precipitated with acetonitrile. Using PER-D5 as internal standard, ultra-high performance liquid chromatography-
tandem mass spectrometry (UPLC-MS/MS) method was adopted. The determination was performed on ACQUITY UPLC HSS T3
C18 column with mobile phase consisted of 0.1% formic acid with 5 mmol/L ammonium acetate-acetonitrile (gradient elution) at the
flow rate of 0.3 mL/min. The column temperature was 40 ℃ , and sample size was 5 μL. The analysis time was 5 min. The
electrospray ionization source and multiple reaction monitoring mode were used for positive ion scanning. The ion pairs used for
quantitative analysis of LTG, LEV, PER and internal standard
