Abstract
Metoprolol succinate-controlled release matrix tablets were made utilizing the wet granulation process with various ratio of Hydroxypropyl methyl cellulose (HPMC K4M). Isopropyl alcohol is used as a granulating agent in the Povidone (PVP K30) solution. In addition to being utilised as diluents to raise the weight of the tablets, magnesium stearate and talc were added to enhance the granules' flow ability during tablet compression. The crushed tablets underwent physicochemical characteristics, in-vitro and kinetic tests, and the micromeritic properties of the generated granules were evaluated. In every formulation, results were nearly satisfactory, with M4 being the best among the others. All of the formulations showed good correlation. The drug diffusion kinetics from matrix tablets appeared to be zero order, and the release mechanism was diffusion regulated.
