The present investigation involves formulation and evaluation of microspheres with Repaglinide as model drug for prolongation of drug release time. An attempt was made to prepare microspheres of Repaglinide by Quasi emulsion solvent diffusion technique, with a view to deliver the drug at sustained or controlled manner in gastrointestinal tract and consequently into systemic circulation. The mic...

Polyoxometalates (POMs) covalently functionalized with methyl methacrylate groups were applied as surfactants in the emulsion polymerization reaction of styrene. Due to the copolymerization of the methyl methacrylate groups and the styrene monomers, the polyoxometalate clusters are covalently grafted onto the surface of polystyrene latex nanoparticles. Such latex particles are fully covered wit...

The aim of this study was to prepare and evaluate microspheres containing ibuprofen. Microspheres were prepared by modified quasi-emulsion solvent diffusion method. The influence of formulation factors (drug-polymer ratio, volumes of solvent, polyvinyl alcohol concentration and type of polymer) on the morphology, particle size distribution, drug loading capacity, micromeritical properties and t...
