ABSTRACT
During the last two decades there has been a remarkable increase in interest in sustained release drug delivery system. This has been due to various factors viz. the extensive cost of developing new drug entities, expiration of existing international patents, discovery of new polymeric materials suitable for prolonging the drug release, and improvement in therapeutic efficacy and safety achieved by this delivery system. A number of design options are available for the preparation of controlled release formulations to modify oral absorption. Formulation approaches are being explored to enhance bioavailability of poorly water-soluble drugs. One such approach that has been shown significantly enhanced absorption of such drugs is to formulate solid dispersionand then formulate its tablets. Solid dispersion technology can be used to improve the in- vitro and in- vivo dissolution properties of slightly water soluble drugs and to control their dissolution rate. In this current study attempts have been made to formulate sustained release tablets of solid dispersions.
