摘要: 目的:研究阿德福韦酯自乳化制剂,探求其最佳处方配比。方法:通过对油相、水、乳化剂的选择和配比优化,成功地将阿德福韦包埋在乳液中,由三元相图得到相应的自乳化区域,并结合自乳化速率、粒径测定、及溶解度试验的考察筛选处方,寻找出最佳的搭配和处方配比。结果:优选的阿德福韦酯自乳化制剂处方中油相为辛酸甘油三酯,表面活性剂为聚氧乙烯(35)蓖麻油。最终确立阿德福韦酯自乳化制剂的最优配方比为:辛酸甘油三酯:聚氧乙烯(35)蓖麻油(7:3)。结论:初步成功地制备了阿德福韦酯自乳化制剂。Abstract: Objective : To search for the optimum formula ratio for the self-emulsifying drug delivery systems of adefovir dipivoxil. Methods : The recipe of the self-emulsifying drug delivery systems of adefovir dipivoxil formation was optimized by studying the pseudo-ternary phase diagram,the self-emulsifying rate,particle size.Adefovir was successfully embedded in the SEDDS emulsion. Results :The optimized prescription was tricaprylin as oil,Cremophor EL35 as surfactant,with the oil and the surfactant ratio was 73. Conclusions :The preliminary adefovir dipivoxil Self-emulsifying prepartion has been prepared.
