Objective: To optimize in vitro transdermal enhancer of odynolysis cataplasms. Method: Franz diffusion cell was adopted with pH 7.4 phosphate buffer as receiving medium
in vitro skin permeation studies of ferulic acid were conducted across excised rabbit abdominal skin.The content of ferulic acid was determined by HPLC to calculate cumulative doses of skin permeation and cumulative penetration rate.Effect of used alone or mixed use of azone
N-methyl-2-pyrrolidone and propylene glycol on in vitro transdermal of ferulic acid was investigated. Result: Optimum transdermal enhancer was 3% azone+3% propylene glycol
it could increase about 2.2 times of transdermal amount of ferulic acid.N-methyl-2-pyrrolidone could hardly increase transdrmal amount of ferulic acid
alone adding 2% azone could increase 1.7 times and 3% propylene glycol increased 1.4 times. Conclusion: 3% Azone+3% propylene glycol could be as transdermal enhancer for odynolysis cataplasms with optimum effect.
