Özet

The aim of this research was to investigate the effect of the duration of ultrasonication energy on the physicochemical characteristics of the nano-sized particulate drug delivery systems. For this purpose, meloxicam-loaded vitamin E d-tocopheryl polyethylene glycol 1000 succinate (TPGS)-emulsified poly (D,L-lactide-co-glycolide) (PLGA) nanoparticles were designed by using ultrasonication-solvent evaporation technique and were characterized by photon correlation spectroscopy for size and size distribution, scanning electron microscopy for surface morphology and laser Doppler anemometry for surface charge. Ultraviolet-spectrophotometer was used to measure the drug encapsulation efficiency and to obtain in vitro drug release profile. The results showed that the physicochemical properties of the prepared nanoparticles are effectively controlled by the amount of shear stress transferred from the energy source to the emulsion, which is strongly correlated to the ultrasonication time.
