The aim of this study was to generate a new chitosan coated insulin nanoliposomes and evaluate their potential for the delivery of insulin. Materials & Methods: Nanoliposomes encapsulated insulin with negative surface charge was prepared by reverse phase evaporation method. For such a preparation, nanoliposomes lecithin, cholesterol, cetyl-diphosphate and β-cyclodexterin were used. Then, nanoliposomes were coated by means of incubation with the chitosan solution. The encapsulation efficiency of the prepared nanoliposomes was measured by spectrophotometry technique after dissolution of the nanoparticles. The hypoglycemic efficacies of chitosan-coated insulin nanoliposomes were investigated by monitoring the blood glucose level after oral administration to diabetic rabbits. Findings: Insulin entrapment efficacy for the prepared nanoliposomes by application of the new formulation was significantly (p CP - IRAN IN - LG - eng PB - sjimu PG - 8 PT - Research YR - 2012
