          摘   要  目的  研究盐酸艾司氯胺酮鼻喷剂在大鼠体内的药动学和牛蛙上颚黏膜的纤毛毒性。方法  大鼠分别经静脉注射盐酸艾
          司氯胺酮溶液和鼻腔给予盐酸艾司氯胺酮后,采用液相色谱串联质谱法测定盐酸艾司氯胺酮的血药浓度,使用Phoenix WinNonlin
          8.1.0软件计算药动学参数。以离体牛蛙上颚黏膜为模型,考察盐酸艾司氯胺酮鼻喷剂给药后上颚黏膜形态,记录纤毛持续摆动
          时间及恢复摆动情况。结果  盐酸艾司氯胺酮经鼻给药后2 min血药浓度达到峰值,峰浓度为(814.58±418.80)ng/mL,药时曲线
          下面积为(203.75±92.76)ng·h/mL,绝对生物利用度为60.68%。给予盐酸艾司氯胺酮鼻喷剂后,牛蛙上颚黏膜纤毛排列整齐,边
          缘清晰,纤毛结构完整且摆动活跃;纤毛持续摆动时间为(178.17±13.30)min,纤毛停止摆动后可恢复,恢复摆动时间为(24.50±
          9.19)min,相对运动百分率约为53.56%。结论  盐酸艾司氯胺酮鼻喷剂起效迅速,生物利用度较高,纤毛毒性较小。

          ABSTRACT    OBJECTIVE  To study the pharmacokinetics of Esketamine hydrochloride nasal spray in rats and ciliary toxicity to
          maxillary mucosa of bullfrog. METHODS The plasma concentration of esketamine hydrochloride in rats was determined by LC-MS/
          MS  after  intravenous  injection  of  esketamine  hydrochloride  solution  and  nasal  administration  of  esketamine  hydrochloride;  the
          pharmacokinetic  parameters  were  calculated  by  using  Phoenix  WinNonlin  8.1.0  software.  Using  the  maxillary  mucosa  of  isolated
          bullfrog  as  a  model,  the  morphological  changes  of  maxillary  mucosa  were  investigated,  and  the  duration  and  recovery  of  ciliary
          oscillation  were  recorded  after  nasal  administration  of  esketamine  hydrochloride.  RESULTS  The  peak  of  blood  concentration
          occurred  2  min  after  nasal  administration  of  esketamine  hydrochloride;  cmax  was (814.58±418.80)  ng/mL, AUC0-∞  was (203.75±
          92.76)  ng·h/mL,  and  the  absolute  bioavailability  was  60.68%.  After  nasal  administration  of  esketamine  hydrochloride,  it  was
          observed  that  the  cilia  of  bullfrog  were  arranged  neatly,  the  edges  were  clear,  the  cilia  tissue  structure  was  complete and  the  cilia
          moved  actively. The  cilia  movement  time  was (178.17±13.30)  min  for  the  first  time,  and  after  the  cilia  moved  again,  the  ciliary
          movement  time  measured  again  was (24.50±9.19)min  with  a  relative  movement  percentage  of  53.56%.  CONCLUSIONS
          Esketamine hydrochloride nasal spray has a rapid onset of action, high bioavailability, and low ciliary toxicity.
