The biopharmaceutical properties of a new drug carrier based on an interpolyelectrolyte complex (IPEC) between Carbomer 940 and Eudragit ® EPO have been studied in the form of a polycomplex matrix system (PMS) intended to be a potential carrier for peroral drug delivery systems. The release profiles of diclofenac sodium from the proposed PMS and Voltaren ® retard in model gastroitestial tract medium belong to the intestine-soluble and sustained-release types, respectively. Evaluation of the pharmacokinetic parameters of the PMS revealed a close in vitro/in vivo correlation. The proposed PMS, in contrast to the parent drug, provides targeted drug delivery to the colon region and is comparable with Voltaren ® retard with respect to the bioavailability and the main pharmacokinetic parameters.Key words: interpolyelectrolyte complex, Carbomer 940, Eudragit ® EPO, polycomplex matrix system (PMS), Voltaren ® retard, in vitro/in vivo correlation. 491 0091-150X/11/4508-0491
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
