| 中文摘要: |
| 目的考察通塞脉微丸中的活性成分在大鼠不同肠段的吸收动力学及微丸与标准品的吸收差异，评价该制剂用药的合理性。方法采用大鼠在体小肠吸收实验方法。结果微丸中活性成分在小肠各部位均能较好地吸收，无特异性吸收部位。不同浓度溶液对甘草苷、阿魏酸和甘草酸铵的吸收无影响；浓度对肉桂酸吸收有差异，可能借助载体转运。结论标准品中甘草苷、甘草酸铵和肉桂酸较微丸吸收快，阿魏酸无显著差异，提示微丸维持药效更持久。 |
| 英文摘要: |
| OBJECTIVE To examine the absorption dynamics of the active components of Tongsaimai Micro-pellet at different portions of the intestine and the absorption differences between micro-pellet and the standard drug and evaluate the rationality of this preparation. METHOD In vivo experiment was used to observe the absorption in rat small intestine.RESULT The active components of Tongsaimai Micro - pellet were well absorbed at different portions of the intestine, with no specific absorption locations. Different concentrations of the solution did not affect the absorption of liquirtin, ferulaic acid and ammonium glycyrrhizinate, but affected the absorption of cinnamic acid. CONCLUSION The liquirtin, ammonium glycyrrhizinate and cinnamic acid in the standard drug are absorbed faster than those in the micro-pellet, but no marked differences were detected in the absorption of ferulaic acid, suggesting the enduring effect of micro-pellets. |
