Formulation research is oriented towards safty, efficiency and quick onset of action of existing drug molecule through novel concepts of drug delivery. Metformin hydrochloride is an oral antidiabetic biguinide agent, used in the management of non-insulin dependent (type-2) diabetes Mellitus. Orodispersible tablets of Metformin Hcl were prepared by direct compression method. About nine formulations for the present study were carried out based on combination of two superdisintegrants. Croscarmellose sodium, crosspovidone and sodium starch glycolate were used as superdisintegrant. The prepared...

The purpose of the present research was to produce a quick/slow biphasic delivery system for Diclofenac Sodium. A dual component tablet made of a sustained release tableted core and an immediate release tableted coat was prepared by direct compression. Both the core and the coat contained a model drug (Diclofenac Sodium). The sustained release effect was achieved with a polymer (Microcrystalline cellulose) to modulate the release of the drug. The in vitro drug release profile from these tablets showed the desired biphasic release behavior: the Diclofenac Sodium contained in the fast releasing...
