ABSTRACT
Objective To optimize the prescription matrix proportion of Bitongning Patch and observe its percutaneous absorption in vitro. Methods U6(66) Uniform design was performed to investigate the influence of scopolamine and aconitine in the proportion for 24 h cumulative permeation in vitro. The drug permeation behavior through excised mouse skin was studied with improved Franz diffusion cell. Results With the matrix ratio for PVA 11.02%, PVP 29.93%, glyceroh 7.42%, azone 4.95%, and propanediol 11.06%, respectively, the Patch had the maximal cumulative permeation amount and cumulative permeation curve coincided with the Higuchi Equation. Conclusion The prescription composition optimized by uniform design meets the requirement of skeleton-controlled transdermal delivery system.
