Intranasal drug delivery bypasses the blood–brain barrier uri icon

abstract

  • LAS VEGAS—The nasal mucosa in the upper third of the nasal cavity provides a direct pathway from the external environment to the brain and, according to William H. Frey II, PhD, that pathway can be used to noninvasively deliver therapeutics into the brain. This pathway effectively bypasses the blood–brain barrier and avoids the systemic exposure and side effects associated with therapeutics that enter the bloodstream. At the 19th Annual Meeting of the North American Neuromodulation Society, Dr. Frey presented an in-depth look at intranasal delivery of therapeutics to the brain.
