摘要
目的:研究芷冰原位凝胶的体外释放行为。方法:以卡波姆为材料制备芷冰鼻腔原位凝胶,考察其中欧前胡素和异欧前胡素的体外释药行为,用Weibull方程对其体外释放结果进行拟合。结果:制备的芷冰原位凝胶体外具有缓释效果,可以持续释药8 h,释放效果随卡波姆用量的增加而降低,其释药行为符合Weibull方程。结论:芷冰原位凝胶的体外释药机制为非Fick扩散。
Objective:To investigate the release profile of Zhibing in-situ gel(ZB-ISG)in vitro.Method: ZB-ISG was prepared by Carbomer,investigated the release behavior of imperatorin and isoimperatorinin vitro,and the results were fitted by weibull equation.Result: ZB-ISG had slowly-releasing effect and could continously release for 8h,and the release effect decreases with the increase of Carbomer.The study showed that all models fitted well with Weibull equation.Conclusion: The releasing mechanism of ZB-ISG is non-Fickian diffusionin vitro.
