Transdermal drug delivery system (TDDS) is not practicable for delivery of materials whose final target is skin itself. Controlled release of drugs onto the epidermis with assurance that the drug remains primarily localized and does not enter the systemic circulation in significant amounts is a challenging area of research. Microsponges are highly porous micro-sized particles with a unique ability for entrapping active pharmaceutical ingredients. To control the delivery rate of active agents to a predetermined site in human body has been one of the biggest challenges faced by scientists. Microsponges are safe biologically and offer unique advantage of programmable release. This technology offers entrapment of ingredients and is believed to contribute towards reduced side effects, improved stability, increased elegance and enhanced formulation flexibility. This technology is being used for topical formulations and also for oral administration. The present review describes microsponge technology including its preparation, characterization, programmable parameters and release mechanism of microsponge drug delivery system.
