Transdermal Permeation of Compound Film Forming Gel in vitro / 中国药师

ABSTRACT

Objective:To study the preparation and in vitro release and transdermal absorption of compound film forming gel. Methods:The compound film forming gel was made from new types of film-forming materials. The in vitro release rate was determined by Franz diffusion cells. Results:The in vitro release rate of mupirocin and dyclonine from the compound film forming gel was 81.34% and 88.46%,the transdermal cumulative release amount was(192.73 ± 0.45) μg·cm-2and(103.58 ± 0.66) μg·cm-2,and the skin retention was (419.81 ± 1.48) μg·cm-2and (212.07 ± 1.81) μg·cm-2, respectively. Conclusion: The release of drug is nearly complete. The transdermal absorption test shows that about 30.26% mupirocin and 32.53% dyclonine can pass through skin, and about 65.91% mupirocin and 66.59% dyclonine are stored in skin. The preparation not only plays the role of bacteriostasis,but also promotes wound healing and analgesia.
