Abstract
N-Palmitoylethanolamide showed great therapeutic potential in the treatment of inflammation and pain but its unfavourable pharmacokinetics properties will hinder its use in the clinical practice. A nanotechnology-based formulation was developed to enhance the probability of N-palmitoylethanolamide therapeutic success, especially in skin disease management. Lipid nanoparticles were produced and characterized to evaluate their mean size, ζ-potential, thermal behaviour, and morphology. The ability of N-palmitoylethanolamide to diffuse across the epidermis as well as anti-inflammatory and analgesic effects were investigated. Particles had a mean size of about 150nm and a ζ-potential of -40mV. DSC data confirmed the solid state of the matrix and the embedding of N-palmitoylethanolamide while electron microscopy have evidenced a peculiar internal structure (i.e., low-electrondense spherical objects within the matrix) that can be reliably ascribed to the presence of oil nanocompartments. Lipid nanoparticles increased N-palmitoylethanolamide percutaneous diffusion and prolonged the anti-inflammatory and analgesic effects in vivo. Lipid nanoparticles seem a good nanotechnology-based strategy to bring N-palmitoylethanolamide to clinics.File | Dimensione | Formato | |
