Abstract

In recent years considerable attention has been focused on the development of new drug delivery systems known as controlled release drug delivery systems. Such interest is based largely on the fact that the controlled release products have established and retained place in the market based on their uniqueness and their clinical advantages in the practices of medicine. The major types of controlled release systems include matrix tablets, floating tablets, swellable tablets,  coated beads, microcapsules and microspheres, mucoadhesive systems, ion exchange resin complexes, osmotic pressure controlled release systems, transdermal systems etc. The principle of floating tablets offers a simple and practical approach to achieve increased gastric residence time to enhance the bioavailability and to obtain controlled release. Floating tablets are designed based on gas generating principle. Design of floating tablets needs a strong matrix forming polymer. Several polymers such as various viscosity grades of hydroxypropylmethyl cellulose (HPMC), Carbopol 934P, Eudragit RL, calcium alginate, chitosan, xanthan gum, guar gum, ethyl cellulose etc., have been used in the design of floating tablets of various active pharmaceutical ingredients (APIs). Though these polymers are available for floating tablets, there is a continued need to develop new, effective and efficient polymers for controlled release floating tablets.The overall objective of the investigation is to develop new, efficient and safe polymer as floating matrix former for floating systems.
