Do the chitosan nanoparticles really augment the drugs’ transdermal fluxes: ending the debate using meta-analysis

Abstract

Introduction Transdermal delivery has been extensively investigated as a successful alternative to the oral and parenteral routes of administration. The use of polymeric nanoparticles as drug delivery systems through this route has always been controversial. The use of meta-analyses is a useful quantitative means to decide upon the efficiency of this type of vehicles transporting drugs through the skin.
