摘要
目的:研究口服抗生素药物左氧氟沙星对中药黄芩苷血药浓度的影响。方法:用HPLC-ECD方法测定左氧氟沙星(30 mg·kg^(-1),po,bid,给药4 d)和黄芩苷(34 mg·kg^(-1),po,给药一次)合并用药组与黄芩苷(34 mg·kg^(-1),po,给药一次)单独用药组大鼠在给予黄芩苷后不同时间的血浆黄芩苷浓度,比较两者的药动学参数。结果:合并用药组中黄芩苷的C_(max)=(485.73±217.57)ng·mL^(-1),AUC_(0-24h)=(5508.49±2374.16)ng·mL^(-1)·h;单独用药组中黄芩苷的C_(max)=(2645.62+601.42)ng·mL^(-1),AUC_(0-24h)=(28952.90±5731.42)ng·mL^(-1)·h。合并用药组的C_(max)和AUC_(0-24h)显著低于单独用药组(P<0.05)。结论:左氧氟沙星严重影响黄芩苷的血药浓度,提醒临床医生和患者应合理用药。
Objective: To study the interference of levofloxacin with absorption of baicalin in rats. Methods: The rats were randomly supplemented with a single close of baicalin alone (34 mg·kg^ -1 ,po) or combination of levofloxacin ( 30 mg·kg^ -1 ,po, bid, for 4 days) with baicalin ( 34 mg· kg^ -1, po, single dose). Plasma concentrations of two groups were monitored by HPLC with electrochemical detection (ECD). The pharmacokinetics parameters were calculated by statistical moment analysis. Results: The pharmaeokinetics parameters of the bi-drugs and mono-drug groups were Cmax (485.73 ± 217.57) vs. (2645.62 ±601.42)ng·mL^-1 and AUC0-24h (5508.49 ±2374.16)vs. (28952.90±5731.42)ng·mL^- 1· h ; the P values showed a statistical difference (P 〈 0. 05 ). Conclusion : Levofloxacin significantly interferes the absorption of baicilin.
