Bi-Directional Nasal Drug Delivery

A new concept in nasal drug delivery looks set to transform the delivery efficiency of nasal spray products. A revolutionary new technology is expected to have a dramatic impact on the delivery of drugs via the nasal route. Traditionally, the development of nasal spray products has been faced with a major dilemma: on the one hand, nasal delivery can be improved by using smaller particles, but on the other, this has to be balanced against the increased risk of drug being inhaled into the lungs. A new concept, bi-directional drug delivery, addresses this dilemma by isolating the nasal circuit from the lungs – enabling particle size, flow rate and direction to be optimized.
