目的：制备布洛芬--细菌纤维素载药膜，并考察布洛芬--细菌纤维素膜的体外释放特性。方法紫外分光光度法测定布洛芬原料药的含量；将布洛芬溶解于乙醇中，并用浸泡法载入细菌纤维素膜；利用紫外分光光度法，考察布洛芬--细菌纤维素膜的体外释放特性。结果布洛芬--细菌纤维素膜的体外释放曲线拟合，更加符合weibul 函数分布，有一定的缓释作用。结论布洛芬原料药用浸泡法可载入细菌纤维素膜，布洛芬--细菌纤维素膜有一定的缓释作用，有望开发为布洛芬的新型缓释药物载体材料。“,”Objective To prepare Ibuprofen-Bacterial cellulose and to investigate its in vitro release characteristics. Method Uv spectrophotometry method was used to determine the content of ibuprofen bulk pharmaceutical chemicals.Ibuprofen was dissolved in ethanol and soak into the bacterial cellulose membrane.Uv spectrophotometric method was used to investigate in vitro release characteristics of Ibuprofen-Bacterial. Results In vitro release curve was more fit ing in line with the weibul formula.Ibuprofen-Bacterial cellulose showed a slow-release ef ect. Conclusion Ibuprofen bulk pharmaceutical chemicals can be soaked into the bacterial cellulose membrane and has a slow-release ef ect.The bacterial cellulose membrane is expected to be developed into a new slow-release drug carrier material for ibuprofen.
