Delivering drugs to the brain has always been a challenging task due to the restrictive
properties of the blood-brain barrier (BBB). Intranasal delivery is therefore emerging as an
efficient method of administration, making it easy to self-administration and thus provides a
non-invasive and painless alternative to oral and parenteral administration for delivering
therapeutics to the central nervous system (CNS). Recently, drug formulations have been
developed to further enhance this nose-to-brain transport, primarily using nanoparticles …
