Galactosylated PLGA nanoparticles for the oral delivery of resveratrol: enhanced bioavailability and in vitro anti-inflammatory activity.

Background: Resveratrol (RES) is a natural anti-inflammatory and antioxidant compound with poor water solubility and oral bioavailability. The present study takes the advantages of nanocarriers combined with a ligand (galactose) anchoring to orally deliver RES in an attempt to improve its bioavailability and pharmacological activity.

Methods: RES-loaded galactosylated nanoparticles (RES-GNPs) were prepared by solvent diffusion technique using poly(lactic-co-glycolic acid), synthesized -oleoyl-d-galactosamine and Tween 80.
