OptiNose, has developed interesting technology for delivery of nasal medication in a more effective fashion that common nasal sprays. The Bi-Directional delivery device uses the power of the patient’s own breath to propel drugs deep into the nasal cavity.
As a matter of fact, a new study comparing the OptiNose powder delivery device against traditional liquid nasal sprays has shown that the Bi-Directional system deposits medication more effectively to the middle and upper posterior regions in the back of the nose. The study involved seven participants that inhaled radiolabeled medication using the two delivery methods, the deposition of which was then assessed using a gamma camera sensitive to the emitted radiation.
