【摘要】：目的:建立LC-MS/MS法同时测定血浆伊潘立酮(iloperidone,ILP)及其两个代谢产物羟基伊潘立酮(hydroxy iloperidone,P88)和伊潘立酮羧酸(iloperidone carboxylic acid,P95)的药浓度。方法:色谱柱为Agilent C8(100 mm×4.6 mm,3.5μm),流动相为乙腈-2 mmol·L-1醋酸铵水溶液(含1.5%甲酸)=28∶72,流速为600μL·min-1,采用ESI源正离子模式,多反应监测方式测定。ILP,P88,P95的监测离子对分别为:m/z 427.2→233.2,m/z 429.2→261.2,m/z 429.2→233.2,内标氘代伊潘立酮(iloperidone-D3,ILP-D3)的监测离子对为m/z 430.2→233.1。结果:血浆ILP,P88和P95浓度分别在0.01~15 ng·m L-1,0.01~15ng·m L-1和0.02~20 ng·m L-1范围内线性均良好,日间、日内精密度均在可接受范围内,提取回收率较高,均大于75%。结论:该方法准确、灵敏度高、重现性好,能够较好地应用于ILP及其两个代谢产物的人体药动学研究。
[Abstract]:Aim: to establish a LC-MS/MS method for the simultaneous determination of plasma epperidone (iloperidone,ILP) and its two metabolites, hydroxy iparidone (hydroxy iloperidone,P88) and epperidone carboxylic acid (iloperidone carboxylic acid,P95). Methods: the chromatographic column consisted of Agilent C8 (100 mm 脳 4.6 mm,3.5 渭 m),) as mobile phase, acetonitrile-2 mmol L-1 ammonium acetate aqueous solution (containing 1.5% formic acid) = 28: 72, and the flow rate of 600 渭 L min-1, was determined by ESI source positive ion mode. The monitoring ion pairs of ILP,P88,P95 are as follows: M / z 427.2 ~ 233.2 m / z 429.2 ~ 261.2 m / z 429.2 ~ (2) N ~ (23 ~ (3.2). The internal standard deuterium dipyridone (iloperidone-D3,) is used as internal standard. The monitored ion pair of ILP-D3 is m / z 430.2 + 233.1. Results: the plasma concentrations of ILP,P88 and P95 were linear in the range of 0.01g / mL ~ (-1) and 0.02o ~ (20) ng 路mL ~ (-1), respectively. The intra-day and intra-day precision were within the acceptable range, and the recovery rate was higher. All are larger than 75. Conclusion: this method is accurate, sensitive and reproducible, and can be applied to the pharmacokinetics of ILP and its two metabolites.
