Novel Oral Drug Delivery Systems for Steroids: Overview and Recent Updates

This review summarises the oral route of drug delivery of steroids. Oral drug delivery is widespread owing to its non-invasive nature which complements high patient compliance. This article summarises the problems associated with oral delivery of steroids including bioavailability. In this review, a brief description of the novel types of drug delivery systems of steroids such as microspheres, nanoparticles, solid lipid nanoparticles, multi-matrix tablets, pellet technology, liposomes are presented. The review also presents the latest innovations and advances that have been achieved in recent years.
