摘要: 目的: 建立人血浆中特非那定的高效液相色谱-电喷雾质谱联用(HPLC ESI-MS)测定方法。方法: 以氟桂利嗪为内标,血浆以2 mol/L NaOH溶液碱化后,经乙酸乙酯提取;选用Phenomenex C18色谱柱(250 mm ×4.6 mm,5 μm),柱温25 ℃;流动相为甲醇-水80∶20(含1 %的冰醋酸和0.5 %的三乙胺),流速1 mL/min ;采用四级杆电喷雾质谱检测器进行定量,选择性正离子检测(SIM),特非那定m z 472,氟桂利嗪m z 203 。结果: 本法线性范围为0.1 ~ 20 ng/mL,最低检测限为0.05 ng mL(S N >3),血浆中特非那定的日内和日间精密度为2.54 % ~ 9.28 %,回收率为88.62 %~ 91.67 %。结论: 本法专属性强、灵敏度高,适用于临床试验中特非那定的药代动力学研究。

Abstract: AIM: To establish a highly sensitive method for the quantitation of terfenadine in human plasma by using high performance liquid chromatogramelectrospray ionization-mass spectrometry (LC-ESIMS).METHODS: Flunarizine was chosen as the internal standard (I.S.) , the plasma was extracted by ethyl acetate after alkalized with 2 mol L sodium hydroxide, and the Phenomenex C18 chromatographic column(250 mm ×4.6 mm, 5 μm) was used, the column temperature was 25 ℃, the mobile phase was methanol-water(80∶20) including 1 %glacial acetic acid and 0.5 % triethylamine.The flow rate was 1 mL/min.Analytes were quantitated using positive electrospray ionization in a quadrupole spectrometer.The selected ion monitoring(SIM) mode was detected , terfenadine m z was 472 and flunarizine m z was 203.RESULTS: The linear range was 0.1 -20 ng mL, the lowest detectable limit was 0.05 ng mL (S N >3) , The intra and inter-assay precision of terfenadine was 2.54 %-9.28 %.The recovery of terfenadine in plasma was 88.62 % -91.67 %.CONCLUSION: The method has strong specificity and high sensitivity and can be used for clinical experiment of terfenadine pharmacokinetic study.
