    Abstract:
    Dexibuprofen loaded pegylated poly(lactic-co-glycolic) nanospheres prepared by solvent diffusion method were designed to increase Dexibuprofen brain delivery reducing systemic side effects. Nanospheres exhibited a mean particle size around 200 nm (195.4 nm), monomodal population and negative surface charge. Drug loaded nanospheres showed a sustained release profile, allowing to modify the posology in vivo. Nanospheres were non-toxic neither in brain endothelial cells nor astrocytes and do not cause blood¿brain barrier disruption. Nanospheres were able to partially cross the cells barrier and release the drug after co-culture in vitro experiments, increasing Dexibuprofen permeation coefficient. Behavioral tests performed in APPswe/PS1dE9 mice (mice model of familial Alzheimer's disease) showed that nanospheres reduce memory impairment more efficiently than the free drug. Developed nanospheres decrease brain inflammation leading to ¿-amyloid plaques reduction. According to these results, chronical oral Dexibuprofen pegylated poly(lactic-co-glycolic) nanosystems could constitute a suitable strategy for the prevention of neurodegeneration.
