The aim of the work was to evaluate in vitro and in vivo the effect of the addition of poly(ethylene glycol) (PEG) to paclitaxel (PTX)-cyclodextrin poly(anhydride) nanoparticles. For this, PTX in poly(anhydride) nanoparticles complexed with cyclodextrins (either 2-hydroxypropyl-β-cyclodextrin or β-cyclodextrin) and combined with PEG 2000 were prepared by the solvent displacement method. Intestinal permeability in vitro and in vivo pharmacokinetic studies in C57BL/6J mice were performed. Nanoparticle formulations containing PTX increased its apparent permeability through rat intestine in vitro in the Ussing chambers, enhancing its permeability 10-15 times compared with commercial Taxol®. In addition, in pharmacokinetic studies, drug plasma levels were observed for at least 24 h leading to a relative oral bioavailability between 60
