【摘要】 目的制备京尼平苷乳膏并考察稳定性。方法利用正交试验设计法筛选适宜基质,筛选了不同的促渗剂、防腐剂制成o/w型的乳膏,采用Franz扩散池对纳米乳的体外透皮特性进行了考察,然后对乳膏的流变学和稳定性进行考察。结果最终处方结果是油相体积分数占33%、乳化剂用量为6%、防腐剂用量为0.3%、京尼平苷占0.5%,乳化温度为80℃。此条件制备的乳膏色泽均匀、质地细腻、渗透性良好、便于涂布;12 h累积渗透量为(212.73±22.76)μg·cm-2。药品在常温(25℃)下连续放置6个月,高温(40℃)和低温(4℃)放置3个月,京尼平苷含量和制剂pH值均符合规定。结论京尼平苷乳膏渗透性良好,性质稳定可靠,可以作为京尼平苷经皮给药新剂型。更多还原

【Abstract】 OBJECTIVE To prepare an o/w type geniposide cream and to investigate its stability.METHODS Appropriate base was selected by uniform design;suitable preservative and penetration enhancer were chosen according the characteristics of the cream.Franz diffusion cell was used to evaluate the transdermal characteristics in vitro;the stability and rheology of the cream were evaluated.RESULTS The optimum matrix was composed of oil phase of volume faction 33%,emulsifying agent 6%,and preservative 0.3%.The content of geniposide was 0.5%.The emulsifying temperature was 80 ℃.The cream was uniform in color,homogeneous,exquisite and easy to spread;12 h cumulative penetration amount was(212.73±22.76)μg·cm-2.The contents and pHs of three batches of samples were in accordance with the quality standard after storage at 40 ℃,25 ℃ and 4 ℃ for 3 months.CONCLUSION Geniposide cream is very stable and has good transdermal characteristics in vitro,which is a new dosage form for transdermal drug delivery.更多还原
