摘要: 目的: 建立液相色谱-串联质谱法(HPLC-MS-MS) 测定人血浆中芬太尼的浓度。 方法: 以D5-芬太尼为内标,采用正己烷处理血浆样品。色谱柱为Thermo Hypurity C18(150 mm×2.1 mm, 5 μm),流动相为甲醇∶水(含 0.1%甲酸)=(85∶15,V/V),流速为 0.3 mL/min,柱温 40 ℃;质谱条件为电喷雾电离源(ESI),检测方式为正离子方式、多离子反应监测(MRM),用于定量分析的离子为芬太尼m/z 337.1→188.1,D5-芬太尼m/z 341.9→187.9。 结果: 芬太尼血药浓度在 19.53~5000 pg/mL 范围内线性关系良好,定量下限为 19.53 pg/mL,日内和日间变异均小于 5.16%,提取回收率均在90%以上;应用此方法研究了24名健康男性受试者使用两种芬太尼透皮贴剂的药代动力学特点,受试制剂对参比制剂的相对生物利用度为(94.0±19.5)%。 结论: 本法具有快速、简便、灵敏、准确等特点,适合人血浆中芬太尼浓度测定。两种制剂生物等效。

Abstract: AIM: To establish an HPLC-MS/MS assay to determine fentanyl in human plasma. METHODS: D-fentanyl was used as an interal standard. Human plasma samples were extracted by n-hexane.The separation was carried out on an Thermo Hypurity C18 (150 mm×2.1 mm, 5 μm) column at 40 ℃.The mobile phase consisted of methanol-0.1% formic acid (85∶15, V/V) at a flow rate of 0.3 mL/min. Electrospray ionization (ESI) source was applied and operated in the positive ion mode. Quantitaion was performed using multiple reaction monitoring (MRM) of the m/z 337.1→188.1 for fentanyl , and m/z 341.9→187.9 for D-fentanyl. RESULTS: The liner calibration curves were obtained in the range of 19.53-5000 pg/mL for fentanyl.The lower limit of quantification was 19.53 pg/mL.The relative standard deviation of the intra-assay and inter-assay precision of variation was less than 5.16%.The extraction recovery for fentanyl was above 90%.To study the pharmacokinetics of two transdermal patches of fentanyl, preparations were given to 24 healthy volunteers, and the relative bioavailability of AUC0-144 was (94.0±19.5)%. CONCLUSION: It is an accurate, sensitive and rapid method that can be applied to determine fentanyl in human plasma.Two preparations of fentanyl are bioequivalent.
