摘 要:目的:研究胡椒碱自乳化释药系统的处方及其体外特性。方法:通过溶解度、处方配伍试验以及伪三元相图的绘制来筛选处方,并考察空白处方、含药处方对自乳化效率的影响以及自乳化后乳滴的粒度分布,考察了胡椒碱自乳化胶囊的溶出速率和稳定性。结果:胡椒碱自乳化胶囊的最终处方为油酸乙酯、Tween 80、Transcutol P,三者之比为30∶55∶15(w∶w∶w),药物为辅料总量的2.5%,粒径约为90 nm,胡椒碱自乳化胶囊60 min溶出度是自制的胶囊剂6倍;低温和常温稳定性考察药物含量无明显变化。结论:所制备的胡椒碱自乳化胶囊自乳化效率高、能力强、性质稳定,体外溶出率高。Objective:To study the optimized formula and characteristics in vitro of piperine self-emulsifying drug delivery system ( SEDDS) . Methods:Solubility test, formula compatibility test and ternary phase diagram were adapted to screen and optimize the for-mula. The effects of the blank formula and piperine-loaded formula on the self-emulsifying efficiency were examined. Meanwhile, the particle size distribution after self-emulsification, and the dissolution rate and stability of SEDDS were determined in vitro as well. Re-sults:The optimized formula was composed of ethyl oleate, Tween 80 and Transcutol P (30:55:15, w/w/w), and the amount of pip-erine was 2. 5% (w/w) of the adjuvants. The mean droplet size was 90 nm approximately. The dissolution profile of SEDDS was 6-fold higher than that of the self-prepared capsules during the 60-minute incubation. There was no significant change in the stability test un-der sub-ambient and ambient temperature. Conclusion:The preparation efficiency of piperine SEDDS is high with promising stability, and the dissolution of the SEDDS capsules is improved obviously when compared with that of the self-prepared capsules.
