Abstract

Some formulations of drug in adhesive transdermal drug delivery systems ()TDDSs)( with different functional and non-functional acrylic pressure sensitive adhesives PSAs)( were prepared. For this purpose fentanyl was used as a drug component. The effects of PSAs type on skin permeation and in vitro drug release from devices were evaluated using hydrodynamically well-characterized Chien permeation system fitted with excised rat abdominal skin. The adhesion properties of devices ()peel strength and tack values)( were obtained. It was found that TDDS with –COOH functional PSA had the lowest steady state flux. Drug release was followed by Higuchi's kinetic model. Adhesion properties of the samples were improved by addition of functional PSA in the formulations.
