          摘   要  目的  建立检测伊布替尼血药浓度的方法并应用于临床。方法  以泽布替尼为内标,血浆样本以固相萃取柱处理后,采用
          高效液相色谱(HPLC)法检测伊布替尼的浓度。以Agilent 5 TC-C18 (2)为色谱柱,乙腈-0.5%磷酸二氢钾溶液(43∶57,V/V)为流动
          相,流速为1 mL/min,检测波长为260 nm,柱温为40 ℃,进样量为20 μL,运行时间为25 min。采用上述方法测定9例非霍奇金淋
          巴瘤患者第30天用药后2 h时血浆中伊布替尼的浓度。结果  伊布替尼检测质量浓度的线性范围为10~500 ng/mL(R =0.998 9),
                                                                                                     2
          定量下限为10 ng/mL;批内、批间精密度试验的RSD均不高于12.77%;提取回收率分别为74.80%、97.70%,RSD均小于2.90%;稳
          定性试验的RSD均小于7.10%。9例患者的血药浓度为15.341~279.628 ng/mL。结论  所建立的HPLC法简单、快捷,可用于伊布
          替尼血药浓度的测定。

          ABSTRACT    OBJECTIVE  To  establish  a  method  to  detect  the  blood  concentration  of  ibrutinib  and  apply  it  to  the  clinic.
          METHODS  Using  zanubrutinib  as  internal  standard,  the  concentration  of  ibrutinib  was  detected  by  high  performance  liquid
          chromatography (HPLC)  after  plasma  samples  were  processed  by  solid-phase  extraction.  The  separation  was  performed  on  an
          Agilent 5 TC-C18 (2) column with acetonitrile-0.5% potassium dihydrogen phosphate solution (43∶57, V/V) as the mobile phase at a
          flow  rate  of  1  mL/min,  a  detection  wavelength  of  260  nm,  a  column  temperature  of  40  ℃,  a  sample  size  of  20  μL,  and  a  run
          time  of  25  min. The  concentration  of  ibrutinib  was  measured  in  the  plasma  of  9  patients  with  non-Hodgkin’s  lymphoma  2  h  after
          drug  administration  on  the  30th  day  by  the  above  method.  RESULTS  The  linear  range  of  the  assayed  mass  concentration  of
          ibrutinib  was  10-500  ng/mL (R =0.998  9),  the  lower  limit  of  quantification  was  10  ng/mL,  and  the  RSDs  of  the  intra-batch  and
                                   2
          inter-batch  precision  tests  were  not  higher  than  12.77%.  The  recoveries  of  the  extraction  were  74.80%  and  97.70%,  with  both
          RSDs<2.90%, and the RSDs of the stability tests were not higher than 7.10%. The peak plasma concentrations of 9 patients were
          15.341-279.628 ng/mL. CONCLUSIONS The established HPLC method is simple and rapid, and can be used for the determination
          of ibrutinib concentration in plasma samples.
