Résumé
Objective:To study the effect of caprylic/capric acid glycerides (Lab), propylene glycol (PG) and Azone on the transdermal behavior of ketoconazole and miconazole nitrate in compound ketoconazole gel, to screen appropriate penetration enhanc-ers. Methods:Using a RYJ-6A-type transdermal drug diffusion tester, the effects of Lab, PG and Azone at different concentrations on the transdermal behavior of ketoconazole and miconazole nitrate in compound ketoconazole gel were studied. Results:3% PG showed the most obvious penetration enhancement, which could increase the permeation of ketoconazole by 2. 004 times, and increase the pen-etration of miconazole nitrate by 1. 795 times, and the differences were statistically significant (P<0. 05). Conclusion:The penetra-tion effect of 3% PG is obvious, which can be applied in compound ketoconazole gel.
