Abstract:

By using resveratrol(RES) and polyethylpyrrolidone(PVP) as raw materials, RES-PVP spherical nanoparticles(RES-PVP NPs) with uniform size were prepared by nano-precipitation method. Then the RES-PVP NPs were loaded into soluble microneedles(MNs) based on hyaluronic acid to prepare the nanodrug-loaded microneedles MN-NPs. The microneedles still maintain high mechanical strength after drug loading, which can meet the needs of penetrating the skin of human scar tissue. The RES-PVP NPs in MN-NPs can induce the apoptosis of human keloid fibroblasts and inhibit their migration. In experiments in vivo, MN-NPs can effectively inhibit the growth of keloid, showing the ability in keloid treatment. The method proposed in this work of transdermal delivery of resveratrol nanodrug using drug-loaded microneedles to treat keloid is feasible, and has good application prospect.

Key words: Resveratrol, Nanodrug, Microneedle, Keloid
