Abstract
The purpose of writing this review was to investigate, compile and present the recent as well as past literatures in more concise way with special focus on approaches which are currently utilized in the prolongation of gastric residence time. One novel approach in this area is Gastro Retentive Drug Delivery System (GRDDSs). GRDDSs can improve the controlled delivery of drugs that have an absorption window by continuously releasing the drug for a prolonged period of time before it reaches its absorption site. These includes floating system, swelling and expanding system, bio/mucoadhesive system, high density system and other delayed gastric emptying devices. The present review addresses briefly about the, factors controlling gastric retention, advantages, Disadvantages and applications of gastroretentive drug delivery systems, Commonly used drug in formulation of GRDDS,Gastroretentive products available in the market, types of GRDDS.
