| 摘 要： | 目的:研究栀子苷溶液的鼻黏膜吸收规律.方法:以大鼠在体鼻循环法为实验模型,考察在不同循环液的体积、流速、药物浓度等条件下栀子苷溶液的鼻黏膜吸收规律.结果:栀子苷在鼻黏膜洗出液中稳定性良好,当循环液体积为5 mL,流速2.5 mL·min~(-1)时栀子苷溶液鼻黏膜吸收速率常数不随药物浓度发生变化.结论:栀子苷溶液鼻黏膜吸收机制为被动扩散,吸收符合一级动力学特点,吸收速率常数K为4.20×10~(-3). |

| Abstract: | Objective: To investigate the regulation of geniposide nasal absorption. Method: We used rat in situ nasal recirculation method as experimental model. The effects of perfusion volume, flow rate, perfusion concentration on nasal absorption of geniposide were studied. Result: Geniposide was stable in rats' nasal lavage solution. At the perfusion volume 5 mL and flow rate 2.5 mL·min-1, the absorption rate of geniposide remains constant in a dose independent manner. Conclusion: The mechanism of geniposide nasal absorption is passive diffusion following first order kinetics and the absorption rate constant is 4.20×10-3. |
| Keywords: | geniposide nasal mucosa absorption in situ rat nasal recirculation method |
