Formulation, evaluation and study of super disintegrants effect on olmesartan medoxomil fast dissolving tablets

The current research was to enhance solubility and dissolution rate of the slightly soluble drug, Olmesartan medoxomil, solid dispersions by physical mixing, solvent evaporation and kneading techniques, with soluplus. The solid dispersions prepared are tested for flow properties, drug content, and particle size. In vitro dissolution studies were carried out to analyse the drug release from solid dispersions. Crystal morphology, drug and polymer interaction for selected solid dispersions was studied by FT-IR and DSC analysis. Fast-dissolving tablets were formulated by using optimized solid dispersions using different concentrations of sodiumstarch glycolate, crosscarmellosesodium, and crospovidone as superdisintegrants using direct compression technique. The tablets prepared are tested for Weight variation, friability, disintegration, content uniformity and harness. The mechanism and kinetics of drug release from the fast-dissolving tablets were tested by in-vitro dissolution studies. The current research proves that combining solid dispersions along with the use of superdisintegrants is novel approach to formulate of Olmesartan medoxomil fast-dissolving tablets.
