[Function of nanoparticles in transdermal and transmucosal drug delivery systems].

Nanoparticles had received much attention in the development of new kind of pharmaceutical formation because of the special nano-effectivity. Recently, some studies discovered the special functions of the nanoparticles in transdermal and transmucosal drug delivery systems. Even though the acting mechanism of the nanoparticles in these drug delivery systems are not known, these discoveries of the special function of the nanoparticles provide new developing prospect to the drug delivery systems. This paper mainly reviews the present studying results about the nanoparticles used in the transdermal and transmucosal drug delivery systems, including the lipid nanopaticles, natural polymer and the synthesized polymer nanoparticles.
