ABSTRACT
In recent years scientific and technological
advancements have been made in the research and
development of rate-controlled oral drug delivery
systems by overcoming physiological adversities, such as short gastric residence times (GRT) and
unpredictable gastric emptying times (GET). Several approaches are currently utilized in the prolongation of the GRT, including floating drug delivery systems (FDDS), also known as hydrodynamically balanced systems (HBS), swelling and expanding systems, polymeric bioadhesive systems, modified-shape systems, high-density systems, and other delayed gastric emptying devices. In this review, the current technological developments of FDDS including
patented delivery systems and marketed products, and their advantages and future potential for oral controlled drug delivery are discussed.
Keywords: FDDS, HBS, floating gastroretentive drug delivery system.
