Abstract

The purpose of this review is to understand the recent literature in the development of expandable drug delivery systems in order to achieve prolonged gastric retention. This review gives the brief about pros and cons of the expandable drug delivery system with the other oral conventional dosage and compares them. This review summarizes about the polymers used, preparation methods, mechanism of drug release and also the methods used to evaluate these systems by In vitro techniques. A special mention is given to the recent marketed and patented products in this review. These systems are the stepping stones for the future development of the pharmaceutical drug delivery systems.
