چکیده    Background: cellulite is the accumulation of subcutaneous fat and connective tissue in tights and buttocks. xanthines,such as aminophylline,are used as phosphodiesterase inhibitors,and are also adenosine receptor antagonists. objectives: the aim of the present study was to characterize in vitro aminophylline transdermal absorption through shed snake skin,and to investigate the absorption enhancing effect of various enhancers. materials and methods: aminophylline gels were prepared using theophylline and ethylenediamine as raw materials of aminophylline,hydroxypropyl methyl cellulose (hpmc) f4m as gelling agent,and propylene glycol as a co-solvent. sodium tauroglycocholate (stgc) (100,200,and 500 μg/ml),lauric acid (1.7 and 15%),and ethanol (60%) were added as enhancers. in vitro percutaneous absorption experiments were performed on snake skin using franz diffusion cells. flux (j),permeability coefficient (p),and enhancement factor (ef) for each formulation were calculated. results: the results indicated that all of enhancers significantly enhanced drug permeability. this effect was decreased by increasing the concentration of stgc; in contrast,by increasing the concentration of lauric acid from 1.7 to 15%,ef was enhanced although ethanol (60%) and stgc (100 μg/ml) showed the highest efs,the effect of ethanol on drug permeability appeared with a lag time. conclusions: according to the findings,type and concentration of penetration enhancers can effect on transdermal permeation of drug. © 2014,school of pharmacy,ahvaz jundishapur university of medical sciences.
