Effect of Azone on Transdermal Absorption in vitro of Dieda Huoluo Microemulsion Spray
Objective:To study the effect of different dosage azone on transdermal absorption in vitro of osthol and methyl salicylate in Dieda Huoluo Microemulsion Spray.Method:The experiment of percutaneous penetration in vitro was operated with the methods of Franz diffusion cell and hairless mice skin
and the penetration quantity of osthol and methyl salicylate was determined by HPLC
and calculate the trandermal rate and lag time.Result:The releasing permeated amount of osthol and methyl salicylate in vitro followed the zero releasing equation.The results showed that the trandermal rate was slower as increased the dosage of azone.Conclusion:The formulation of microemulsion and volatile oil in preparation contributed to the good transdermal absorption in vitro of osthol and methyl salicylate.It’s not necessary to add azone to the preparation.
