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.
