TITLE: Effects of Yiru tiaojing granules on the pharmacokinetics of olanzapine in rats
摘要: 目的 探讨抑乳调经颗粒对奥氮平在大鼠体内药动学的影响。方法分别按单剂量给药和多剂量给药,将SD大鼠随机分4组,每组6只。A、B组大鼠分别单次灌胃奥氮平(5mg/kg)、奥氮平(5mg/kg)+抑乳调经颗粒(0.972g/kg);C、D组大鼠同法给药,每天1次,连续给药14d。分别在给药前及末次给药后5、15、30min和1、2、3、6、8、12、24h于大鼠眼眶静脉丛采血,采用液相色谱-质谱技术测定大鼠的血药浓度,采用DAS2.0软件计算药动学参数。结果与A组比较,B组大鼠24h内的药-时曲线下面积(AUC0-24h)、AUC0-∞、峰浓度(cmax)均显著降低(P<0.05),24h内的平均滞留时间(MRT0-24h)、MRT0-∞、表观清除率(CLz/F)均显著延长(P<0.05);C组与D组大鼠的药动学参数比较,差异均无统计学意义(P>0.05)。结论单次联用抑乳调经颗粒会抑制奥氮平在大鼠体内的吸收,长期联用抑乳调经颗粒对奥氮平的药动学过程无明显影响。
ABSTRACT: OBJECTIVE To investigate the effects of Yiru tiaojing granules on the pharmacokinetics of olanzapine in rats. METHODS SD rats were randomly divided into 4 groups according to single-dose administration and multiple-dose administration, with 6 rats in each group. Groups A and B were given olanzapine (5 mg/kg) or olanzapine (5 mg/kg)+Yiru tiaojing granules (0.972 g/kg) in a single gavage, and groups C and D were administered with the same method once a day for 14 d. Blood was collected from the orbital venous plexus before administration and 5, 15, 30 min and 1, 2, 3, 6, 8, 12, 24 h after the last administration, respectively. The blood concentration was determined by LC-MS, and the pharmacokinetic parameters were calculated by using DAS 2.0 software. RESULTS Compared with group A, group B showed a significant decrease in AUC0-24 h, AUC0-∞ and cmax (P<0.05), and a significant prolongation of MRT0-24 h, MRT0-∞ and CLz/F (P<0.05); there was no statistically significant difference in the pharmacokinetic parameters between group C and group D (P>0.05). CONCLUSIONS A single administration of Yiru tiaojing granules can inhibit the absorption of olanzapine in rats, and long-term administration of Yiru tiaojing granules does not have a significant effect on the pharmacokinetic process of olanzapine.
