In the present study, solid dispersion nanoparticles with a hydrophilic polymer and surfactant were developed using the supercritical antisolvent (SAS) process to improve the dissolution and oral absorption of megestrol acetate. The physicochemical properties of the megestrol acetate solid dispersion nanoparticles were characterized using scanning electron microscopy, differential scanning calo...

The purpose of this study is to develop and characterize the nature of a solid dispersion system of nifedipine in a polymer matrix consisting of PVP K30 and poloxamer 407. Dispersions consist of drug, polymeric carrier and surfactant carrier. Binary solid dispersions consisting of nifedipine and PVP K30 were developed by solvent evaporation method. Poloxamer 407, surfactant carrier was incorpor...

Meloxicam is a poorly water soluble non steroidal anti-inflammatory drug and antipyretic agent. The aim of the present work was to investigate the effect of different types of carriers on in vitro dissolution of meloxicam. Meloxicam solid dispersions were prepared by physical mixing, co-grinding and solvent evaporation methods with polyethylene glycol (PEG) 6000. The effect of solubilization by...

PURPOSE The aim of the present investigation was preparation and characterization of sirolimus solid dispersions by solvent evaporation technique to improve its dissolution properties. METHODS Polyvinylpyrrolidone (PVP), Poloxamer 188 and Cremophore RH40 were used to prepare the solid dispersions of sirolimus. In vitro dissolution study using USP type I apparatus, were performed in distilled ...

Eplerenone, a BCS class II drug with low bioavailability and t1/2 of 3-6 hrs is primarily used to treat Congestive Heart Failure (CHF) hypertension. So, develop the biological performance solid dispersion along oral disintegrates was prepared by employing HP ?-Cyclodextrin ?-Cyclodextrin. Eplerenone dispersions were repared various carriers in varying ratios carrier respectively (0.5:1, 1:1 1.5...
