摘 要:目的:制备卡维地洛(CA)传递体,并进行质量评价。方法:采用薄膜分散法联合高压乳匀法制备CA传递体;高效液相色谱法测定其中CA的含量;SephadexG-50凝胶柱层析法测定其中CA的包封率;对CA传递体的外观、形态、粒径及电位进行考察。结果:制备的CA传递体为乳白色、近均一透明的胶体溶液;CA平均含量为27.09μg·mL-1,平均包封率为80.84%,RSD均<2.0%;体系粒径在100nm左右,多分散性系数为0.05左右,电位均>41mV,具有较好的质量和稳定性。结论:CA传递体制备工艺可行、方法简单、质量可控。OBJECTIVE: To prepare Carvedilol transfersomes, and to evaluate the quality of it. METHODS: Carvedilol trans-fersomes were prepared by film dispersion and high-pressure homogenization. The content of carvedilol was determined by HPLC, and the entrapment efficiency of carvedilol transfersomes was determined by using Sephadex G-50 chromatography; the appear-ance, shape, particle size and Zeta potential of transfersomes were evaluated. RESULTS: Carvedilol transfersomes were colloid so- lution in ivory white color, nearly uniform and transparent. The average content of carvedilol was 27.09 μg·mL^-1, and average en- trapment efficiency was 80.84% (all the RSD〈2.0% ) ; the particle size was about 100 nm, polydispersity index was about 0.05, the Zeta potential was more than 41 mV. The preparation had good quality and stability. CONCLUSION: The preparation technolo-gy of Carvedilol transfersomes is feasible, simple and controllable in quality.
