Paper Abstract

In this research poly (d,l-lactide-coglycolide acid) (PLGA) as polymeric nanospheres, poly(vinyl alcohol) (PVA) with 87-89% hydrolysis degree as surfactant and distilled water as suspending medium were used. The encapsulated drug was Bethametasone. The nanospheres were prepared by an emulsion-solvent evaporation method. The nanospheres characterized by photon correlation spectroscopy (PCS) and scanning electron microscopy (SEM). The amount of drug release was determined by HPLC. In emulsion-solvent evaporation technique, time of ultrasound exposure, surfactant content in the formulation and evaporation rate of organic solvents were considered as formulation variables.
