Abstract It remains a challenging task to enhance the drug delivery across blood-brain barrier in pharmaceutical research. At present research is focused on two routes: nanoparticles(i.v.) and nasal delivery route. The following advances are reviewed in the present article: preparation methods of drug-loaded nanoparticles and the mechanism of crossing blood-brain barrier of nanoparticles; the routes of circumventing blood-brain barrier by intranasal administration, factors of influencing the delivery of drug into central nervous system from olfactory region, the possibility for macromolecular drug to utilize the nasal delivery route.
Key words Blood-brain barrier;Nanoparticles;Nasal delivery
