摘 要:目的:制备盐酸黄连素生物黏附包衣片并研究其性质。方法:采用正交设计法,确定生物黏附材料羟丙基甲基纤维素、卡波姆934P的用量及配比与制剂体外释放度及黏附力的关系,并对释放度进行释药动力学模拟,根据各模型拟合的残差平方和(Re)、赤池信息准则计算值(AIC)和拟合度(r)值来研究其释药规律。根据Peppas方程特征参数判断其释药机制。结果:羟丙基甲基纤维素与卡波姆对阻滞药物的释放及黏附力影响较大,且卡波姆的效果强于羟丙基甲基纤维素。生物黏附包衣片以Hixson-Crowell方程拟合最佳,药物释放机制为非Fick扩散。结论:盐酸黄连素生物黏附包衣片具有良好的黏附性能和pH依赖性。OBJECTIVE: To prepare Berberine hydrochloride bioadhesive-coated tablet and study its property. METHODS: Orthogonal design was used to determine the relation of the amount as well as proportion of hypromellose and Carbomer 943P with in vitro release and adhesive force of the tablets. The value of fitting Re,AIC and r were used as comprehensive indexes to select the best imitating model. And the release mechanism was determined according to the parameters of Peppas equation. RESULTS: Hypro- mellose and Carbomer 943P significantly inhibited the drug release and adhesive force. Further more, Carbomer 943P had greater effect than hypromellose.Hixson-Crowell equation was the best choice for imitating the release rate in vitro. The release mechanism was proved to be non-tick diffusion. CONCLUSION: Berberine hydrochloride bioadhesive-coated tablet has sound adhesive force and oH denendence.
