摘要: 目的: 研究β-七叶皂苷钠在脑缺血再灌注大鼠体内的药代动力学规律。方法: 应用酶联免疫吸附分析(ELISA, enzyme-linked immunosorbent assay) 检测方法, 测定正常大鼠及脑缺血大鼠经静脉注射β-七叶皂苷钠5 mg·kg-1后β-七叶皂苷钠的血药浓度,并对其药物代谢动力学参数进行研究。结果: 脑缺血再灌注及正常大鼠静脉注射β-七叶皂苷钠5mg·kg-1后, 其药代动力学模型符合二室模型。正常大鼠在静脉注射β-七叶皂苷钠后, 血药浓度迅速下降, 大约20 min 后, 其血浆药物浓度已下降50 %,T1/2α=0.343 h, T1/2β =23.325 h 。约2 h 后, 血浆药物浓度下降速率减慢。而脑缺血再灌注大鼠脑缺血30 min 后, 静脉注射β-七叶皂苷钠后, 其体内药物代谢规律与正常大鼠不同, 药物的代谢速率减慢, 且在3 h 出现一个较低的血药浓度峰, 随后血浓下降。结论: β-七叶皂苷钠在脑缺血再灌注大鼠体内的消除较正常大鼠慢, 在体内停留的时间较长。提示β-七叶皂苷钠在临床的对症治疗时应考虑其药代动力学的特点。

Abstract: AIM: To investigate the pharmacokinetics of sodium β-aescinate in cerebral damage rats induced by ischemia-reperfusion by the developed method of ELISA (enzyme-linked immunosorbent assay). METHODS: After iv injection of sodium β-aescinate (5 mg·kg-1), the plasma concentration was determined. The pharmacokinetic parameters were accessed by the DAS. RESULTS: The profile of the plasma concentration-time was fitted with two-compartment model either in normal or in cerebral ischemia-reperfusion rats. In normal rats, T1/2α= 0.343 h, and T1/2β =23.325 h. In cerebral ischemiareperfusion, T1/2α =0.854 h, and T1/2β =34.283 h. CONCLUSION: The clearance of sodium β-aescinate in cerebral ischemia-reperfusion rats is obviously slower than that in normal rats. The pharmacokinetics of sodium β- aescinate is necessary to consider under the pathologic condition when it is used in treatment of patients of cerebral ischemic disease.
