Study of Azone in Percutaneous Permeation of Compound Tinidazole Gel / 中国药房

ABSTRACT

OBJECTIVE:To study the enhancing effects of azone at different concentrations on percutaneous permeation of compound tinidazole gel and to find out the best concentration.METHODS:Using vertical Franz-type diffusion cell and dif?ferent concentrations of azone as enhancer,the concentrations of tinidazole,chloramphenicol and salicylic acid in permeation solution were measured by RP-HPLC,then cumulative permeation quantity(Q)was calculated.RESULTS&CONCLUSION:Azone at different concentrations could promote the permeability of3ingredients of compound tinidazole gel,and2%azone had the most obvious permeation-enhancing effect.
