Philly.com recently looked at the new nasal delivery system, OptiNose, that is powered by the users breath to more effectively deliver medications. This device has the potential to improve drug effectiveness, reducing dosages, and even ending injection of vaccines.
This device is so effective because:
Blowing air through the mouth triggers the automatic closing of the airway that connects the nasal passages to the lungs and throat, Mahmoud said.
With the nasal passages sealed, spray material is more effectively dispersed throughout the nasal cavity, a large hollow behind the nose lined with membranes that can quickly absorb and move drugs into the blood.
