Design and evaluation of sustained release matrix tablets of glimepiride based on combination of natural and synthetic polymers.

ABSTRACT

The present research work was aimed to develop matrix tablets of Glimepiride with Aloe barbadensis miller leaves mucilage and Povidone and to study its functionality as a matrix forming agent for sustained release tablet formulations. Physicochemical properties of dried powdered mucilage of Aloe barbadensis miller mucilage and Povidone tablet blend were studied. Various formulations of Glimepiride Aloe barbadensis miller mucilage and Povidone were prepared. They found to have better satisfactory physicochemical properties with low SD values. The swelling behavior and release rate characteristics were studied. The dissolution study proved that the dried Aloe barbadensis miller mucilage and Povidone combination can be used as a matrix forming material for making Sustained release matrix tablets.
