In this study, we formulated and investigated the Temozolomide (TM) loaded PLA Lactic acid (PLA) nanoparticles prepared by solvent evaporation technique. The prepared nanoparticles were characterized by using X-Ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM). Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) and Differential scanning colorimetry which showed that such
nanoparticles had a smooth surface and a spherical geometry. Result indicated that Temozolomide trapped in the nanoparticles existed in an amorphous or disordered-crystalline status in the polymer matrix. The release profiles of Temozolomide from nanoparticles resulted in biphasic patterns. After an initial burst, a continuous drug release was observed for up to 1 month.
Keywords: Temozolomide (TM); PLA, Emulsifying-solvent evaporation; Nanoparticles.
