          ABSTRACT   OBJECTIVE To establish and apply a method for the determination of plasma concentration of delamanid (DLM).
          METHODS  After  plasma  samples  were  treated  with  methanol  precipitation,  LC-MS/MS  was  adopted  to  determine  the  plasma
          concentration  of  DLM.  The  chromatographic  column  was  Phenomenex  Synergi   Fusion-RP  with  mobile  phase  of  methanol-0.1%
                                                                      TM
          formic  acid  solution (gradient  elution).  The  column  temperature  was  40  ℃,  the  flow  rate  was  0.3  mL/min,  and  the  sample  size
          was  1  μL.  The  ion  source  was  electrospray  ion  source,  and  positive  ion  scanning  was  carried  out  in  multi-reaction  monitoring
          mode.  The  DLM  ion  pair  used  for  quantitative  analysis  was  m/z  535.0→352.0.  The  plasma  concentration  of  DLM  in  6  multidrug
          resistant  tuberculosis (MDR-TB)  patients  were  determined  by  the  LC-MS/MS  method.  RESULTS  The  linear  range  of  DLM  was
          0.05-8  μg/mL (r=0.999  5),  and  the  lowest  limit  of  quantitation  was  0.05  μg/mL.  RSDs  of  intra-batch  and  inter-batch  precision
          were  all  less  than  10%.  The  accuracy  ranged  92.7%-104.9%.  Average  matrix  effect  was  94.3%-107.5%.  Average  recoveries  were
          93.2%-98.1%. The plasma concentration of DLM in 6 MDR-TB patients ranged from 0.61-2.76 μg/mL, with an average of (1.67±
          0.74)  μg/mL.  CONCLUSIONS  The  established  LC-MS/MS  analysis  method  has  good  specificity,  high  sensitivity,  accuracy  and
          precision, and can be used to determine DLM plasma concentration in MDR-TB patients.
