| 中文摘要:目的 制备盐酸小檗碱纳米乳，优选其处方组成和制备工艺，并对其外观、粒径及体外释放行为等进行评价。方法 采用水滴加法制备盐酸小檗碱纳米乳，绘制纳米乳伪三元相图。选择星点设计-效应面法对纳米乳处方进行优化，确定最优处方组成比例。对制备的盐酸小檗碱纳米乳的粒径、电位、外观形态、体外释药行为等进行表征。结果 确定了盐酸小檗碱纳米乳的最优处方为油相Capryol 90占体系的32.84 %，表面活性剂吐温-80占体系的33.90 %，助表面活性剂1,2-丙二醇占体系16.95 %，水相占体系15.25 %，制备的纳米乳呈澄清透明、形状规则、大小均一的球状，平均粒径为(68.85±8)nm，多分散系数为(0.245±0.03)，载药量为0.83 mg/g。纳米乳的体外释药行为考察，表明其具有一定的缓释效果，其体外释药行为符合一级释放动力学方程。结论 本研究制备的盐酸小檗碱纳米乳可为该药的临床用药提供新的给药剂型。 |

| Abstract:Objective To prepare berberine hydrochloride nanoemulsion, optimize its formulation composition and preparation process, and investigate its in vitro characteristics. Methods BBR-NE was prepared by water drop addition and pseudo-ternary phase diagram was drawn. The formulation of NE was optimized by central composite design-response surface methodology to choose the optimal formulation composition. The particle size, potential and appearance of the prepared BBR-NE were characterized. Results The optimal prescription of BBR-NE was determined as the oil phase Capryol 90 accounted for 32.84% of the system, the surfactant Tween-80 accounted for 33.90%, the co-surfactant 1,2-propylene glycol accounted for 16.95%, and water relative system accounted for 15.25%. The prepared NE was clear and transparent in appearance, regular in shape and uniform in size, with an average particle diameter of (68.85±8) nm, polydiseperse index of (0.245±0.03) and drug loading of 0.83 mg/g. The in vitro drug release results of NE showed that the in vitro drug release behavior was passive diffusion, which had a certain slow releasing effect and met the first-order release equation. Conclusion The BBR-NE can provide a new dosage form for the clinical use of berberine. |
