ABSTRACT Enormous researches have been carried out in the field of topical drug delivery and microsponge drug delivery system is one such approach. Microsponge drug delivery system discovered in 1987 is one that can suspend or entrap a wide range of active ingredient and then be incorporated into a formulated product such as a gel, cream, liquid or powder.
