Abstract
A method and apparatus for nasal drug delivery comprises a first tube in fluid communication with a means for generating a negative pressure and a second tube in fluid communication with an aerosol. The first tube is contacted with one nostril, the said second tube is contacted with the other nostril, and a negative pressure is applied to the first tube, producing a negative pressure within a nasal cavity and causing the aerosol to be drawn into the nasal passages and to deposit on an internal nasal surface.
