A review on floating drug delivery system

Development of microspheres is a promising technology for controlled release and drug targeting. Various types of microspheres such as bio-adhesive, magnetic, floating, radioactive and polymeric microspheres are developed for various purposes. Microspheres occupied a central place in novel drug delivery. There are various departments of medicine like cancer, pulmonary, cardiology, radiology, gynecology, and oncology etc., where numerous drugs are used and are delivered by various types of drug delivery system. Among them microspheric drug delivery system has gained enormous attention due to its wide range of application as it covers targeting the drug to particular site. The purpose of the review is to study the advantages, disadvantages of floating microspheres along with their formulation and evaluation parameters.
