Objective: To study the permeability of paeoniflorin with enhancer azone. Method :Wistar rats as experimental animal models
cutaneous microdialysis technique was used in penetration studies. The in vitro recovery of the probe was assessed by concentration difference method and in vivo recovery was estimated by retrodialysis method. Result: Azone could significantly increase drug permeability
with 1%
3% and 5% azone transdermal delivery was 0.906 9
1.887 8 and 1.272 8 μg ·h-1. Conclusion: Azone is an excellent enhancers for cutaneous absorption of paeoniflorin
and the penetration effect and the concentration will not be linear. The cutaneous microdialysis is a effective method for in vivo cutaneous penetration study.
