Abstract
We report here a comparative study of the release of model drug diclofenac sodium from samples of interpolyelectrolyte complexes IPEC in in vitro conditions on a rotating basket apparatus and in vivo in experiments in rabbits The study IPEC were prepared using different grades of Carbopol® polymer C71g C2020 and Noveon® AA1 and oppositely charged polyelectrolytes – Eudragit® EPO or the natural polysaccharide lowviscosity chitosan These studies demonstrated the potential for IPEC samples based on Carbopol® as a new modifiedrelease drug delivery system At the same time assessment of bioadhesive properties provided evidence of the potential for using IPEC based on C2020/EPO as a mucoadhesive carrier
