Bilayer Floating Tablet : A Novel Floating Tablet

Out of various drug delivery system the novel drug delivery system is overcomes and then physiological problems of gastric retention by decreasing fluctuations in blood drug concentration level with consequent reduction in the undesirable toxicity and poor efficiency. Approaches have their been introduced to prolong gastric residence time such as the floating system, modified shape, swelling index, expanding system and high density system. Two layer floating drug delivery system is combined principle of bilayer tablet as well as floating mechanism. Bilayer floating tablet is new in the era for the successful development of the controlled release formulation along with the different features to provide a way of successful drug delivery system. The purpose of this paper is to the following Review of the principle of floating drug delivery system, current technology used in the development of same as well as summarizes in the applications, advantages and disadvantages, characterization, evaluation methods and future potential for the bilayer floating tablets
