Microsponges: An Advanced Drug Delivery System

Abstract

In the field of drug delivery system, there are so many new formulation techniques. Microsponges are one of the recent unique techniques which are gaining popularity now days due to their use of controlled release and targeted drug delivery system. Microsponges hold a certification as one of the potential approaches for gastric retention where many oral dosage forms face several physiological restrictions due to non-uniform absorption pattern, inadequate medication release and shorter residence time of the dosage form in the stomach. This article presents broad review of microsponges delivery system discussing the principle and preparation method. Appropriate analytical technique for characterization of microsponges like particle size and its distribution, morphology, porosity, surface, density are covered.
