PURPOSE: The objective of the present study was to develop the membrane controlled transdermal systems of glibenclamide and to evaluate with respect o various in vitro and in vivo parameters. METHODS: The membrane moderated transdermal systems were prepared using drug containing carbopol gel as reservoir and ethyl cellulose, Eudragit RS-100, Eudragit RL-100 and Ethylene vinyl acetate (EVA)(2%, 9% and 19% vinyl acetate content) rate controlling membranes. The possible interaction between drug and polymer was studied by IR spectroscopy, DSC and HPTLC analysis. The formulations were subjected to various physicochemical studies, in vitro drug release studies and permeation studies through mouse skin. The blood glucose reducing hypoglycemic activity of the systems was studied in both normal and diabetic mice. Various biochemical parameters and histopathological studies were carried …
