ABSTRACT

The main object of any drug delivery system is to bring about the desire concentration of the drug in blood or tissue, which is therapeutically effective and non-toxic for a prolong period. The recent research and developement of FDDS(Float drug delivery system) affect gastric retention, approaches to design single unit and multiple unit floating systems. Floating beads are used for controlled drug release as they have gastroretentive properties without affecting the gastric emptying rate. This can be achieved by using natural polymers.

Keywords: Introduction, advantages, disadvantages, mechanism of floating drug delivery system, types, preparation, evaluation, application.
