Formulation and characterization of mucoadhesive cellulose- alginate nanoparticle based in situ hydrogel for ocular drug delivery

Abstract

Novel drug delivery system are continually being developed to defeat the low bioavailability observed in many standard ophthalmic formulations. These novel systems are incorporated for the development of hydrogel. For ocular drug delivery system hydrogels are favourable therapeutic material due to their high hiocompatibility and biodegradable characteristics and they are able to increased drug address time and undergo release of drugs
