Floating drug delivery system: an updated review

ABSTRACT

Recent technological and scientific research has been devoted to the development of rate controlled drug delivery systems to overcome physiological adversities such as short gastric residence times and unpredictable gastric emptying times. The floating or hydro-dynamically controlled drug delivery systems are useful in such application. The present review addresses briefly about the floating drug delivery systems. This review also summarizes the in vitro techniques, in vivo studies to evaluate the performance and application of floating systems, and applications of these systems. These systems are useful to several problems encountered during the development of a pharmaceutical dosage form.
