祖师麻凝胶膏剂制备工艺研究

Optimization of Preparation Technology for Zushima Gel Cream

目的优选祖师麻凝胶膏剂的制备工艺。方法以感官评价、初黏力、持黏力和剥离强度评分的综合评分为考察指标,以搅拌时间、炼合温度、搅拌速度、药粉加入顺序为考察因素,采用正交试验进行成型工艺优选。结果祖师麻凝胶膏剂的最佳制备工艺为:祖师麻药粉加入聚丙烯酸钠NP-700和甘油中,搅拌时间为5 min、炼合温度为40℃、搅拌速度为100 r/min。结论优选工艺制备的祖师麻凝胶膏剂持粘力、光泽性、赋型性均较好,制备工艺良好。

Objective To optimize preparation process of Zushima Gel Cream. Methods The comprehensive evaluation set sensory evaluation, initial adhesive force, viscous force, and peeling strength score as indexes. The mixing time, refining temperature, mixing speed, and powder adding sequence were investigation factors. Orthogonal experiment was used to optimize forming process. Results Conditions of optimized preparation process were as following： add Zushima powder in Viscomate NP-700 and glycerol; mixing time was 5 min; refining temperature was 40 ℃; mixing speed was 100 r/min. Conclusion The preparation process is good and optimized Zushima Gel Cream has a good adhesive force, good glossiness and excipients. The preparation process is good.
