摘要
目的:制备盐酸西替利嗪凝胶剂,研究其体外透皮特性。方法:以卡波姆940为辅料制备西替利嗪凝胶剂,采用改良Franz扩散池,以离体大鼠皮肤为透皮屏障,采用HPLC法测定西替利嗪的透皮行为。结果:西替利嗪凝胶体外透皮释药方程为Q=110.03t+17.17(r=0.99),透皮速率为110.03μg/(cm2.h)。结论:西替利嗪凝胶具有良好的透皮效果,其体外经皮渗透符合一级动力学过程。
Objective：To prepare cetirizine hydrochloride gel and study its skin penetration in vhro. Methods： Cetirizine gel was prepared with carbopol 940 as base material. Using Franz diffusion cell and excised rat skin in vitro as transdermal barrier. The cumulative permeation quantity of cetirizine was determined by HPLC. Results：The penetration equation of eetirizine gel was Q = 110. 03t ＋ 17. 17 （r = 0.99）. Conclusion：The penetration of cetirizine from the gel through the rat skin followed first-order kinetics.
