          摘  要  目的  考察氯吡格雷对大鼠体内环泊酚药动学和药效学的影响。方法  18只雄性SD大鼠随机分为对照组、氯吡格雷正
          常剂量组和氯吡格雷高剂量组,每组6只。氯吡格雷正常剂量组和氯吡格雷高剂量组大鼠分别灌胃7.5、15 mg/kg的氯吡格雷,对
          照组大鼠灌胃同体积的0.5%羧甲基纤维素钠溶液,每天1次,连续给药14 d后于大鼠尾静脉注射环泊酚2.4 mg/kg。在结束注射
          后2、4、8、12、16、20、30、45、60 min时于眼内眦取血,统计各组大鼠的翻正反射消失(LORR)持续时间。大鼠血浆经乙腈沉淀蛋白
          后,以氘代环泊酚为内标,以Symmetry C18为色谱柱,以乙腈-含5 mmol/L乙酸铵的0.01%氨水溶液(梯度洗脱)为流动相,采用液相
          色谱-串联质谱法检测血浆中环泊酚的质量浓度,采用DAS 2.0软件计算各组大鼠的药动学参数。结果  与对照组比较,氯吡格雷
          正常剂量组和氯吡格雷高剂量组大鼠体内环泊酚的药时曲线下面积和平均驻留时间均显著增加或延长,血浆清除率均显著降低,
          LORR持续时间分别延长了19.5%和23.9%,差异均有统计学意义(P<0.05)。氯吡格雷两个剂量组大鼠体内环泊酚药动学参数
          和 LORR 持续时间比较差异均无统计学意义(P>0.05)。结论  氯吡格雷可抑制环泊酚的体内代谢,并延长大鼠的 LORR 持续
          时间。

          ABSTRACT   OBJECTIVE To investigate the effects of clopidogrel on the pharmacokinetics and pharmacodynamics of ciprofol in
          rats. METHODS Eighteen male SD rats were randomly divided into control group, clopidogrel normal-dose group and clopidogrel
          high-dose group, with 6 rats in each group. Among them, rats in the normal-dose group and high-dose group were given 7.5 mg/kg
          and  15  mg/kg  clopidogrel  by  gavage,  respectively,  and  rats  in  the  control  group  were  given  the  same  volume  of  0.5%  sodium
          carboxymethyl cellulose solution, once a day, for 14 consecutive days. Afterward, 2.4 mg/kg ciprofol was injected by tailvein and
          blood  samples  were  collected  from  the  inner  canthus  of  the  eye  at  2,  4,  8,  12,  16,  20,  30,  45  and  60  min  after  the  end  of  the
          administration. During this period, the duration of the loss of righting reflex (LORR) in rats was counted. After the proteins were
          precipitated  by  acetonitrile,  the  rat  plasma  sample  was  analyzed  by  LC-MS/MS  using  deuterated  ciprofol  as  the  internal  standard,
          Symmetry  C18  as  the  chromatographic  column,  and  acetonitrile-0.01%  ammonia  solution  containing  5  mmol/L  ammonium  acetate
         (gradient elution) as the mobile phase to detect the concentration of ciprofol in the plasma. The pharmacokinetic parameters in rats
          were calculated by using DAS 2.0 software. RESULTS Compared with control group, area under the drug concentration-time curve
          and  mean  residence  time  of  ciprofol  increased  or  prolonged  significantly,  while  plasma  clearance  decreased  significantly  in
          clopidogrel  normal-dose  and  high-dose  groups;  the  duration  of  LORR  in  rats  was  prolonged  by  19.5%  and  23.9%,  with  statistical
          difference (P<0.05).  However,  there  was  no  statistically  significant  difference  in  the  pharmacokinetic  parameters  or  LORR
          duration  of  ciprofol  between  the  different  dose  groups  of  clopidogrel (P>0.05).  CONCLUSIONS  Clopidogrel  could  inhibit  the
          metabolism of ciprofol in rats and prolong the duration of LORR.
