Modulated transdermal delivery of nonsteroidal anti-inflammatory drug by macroporous poly(vinyl alcohol)-graphene oxide nanocomposite films

In this study, a facile, economically feasible, and scalable approach to fabricate macroporous poly(vinyl alcohol)-GO (PVA-GO) nanocomposite films with varying filler loadings was demonstrated. The nanocomposite films were prepared using a solvent casting process and employed as a diffusion layer for modulating the transdermal delivery of an anti-inflammatory drug (i.e., ketoprofen). The diffusion membrane was assembled in a three-layer...
