A Promising Oral Drug Delivery System of Microsponges: A Brief Review

Abstract

In the modern era of drug delivery, microsponges have their own tremendous properties of porous nature, due to this porous nature they have a capacity to entrap active drug and acts as a drug carrier because of this entrapment controlling the drug release and targeting the drug to a particular site is possible. Initially, this microsponge drug delivery has been used for topical route and later on oral route, recently, researches focused on the pulmonary and parenteral route of delivery. The present review aims at the development of microsponge technology in oral drug delivery, preparation, formulation considerations, characterization, recent advancements, and future prospects of microsponge drug delivery.
