FIG. 3. — Droplet size distribution profile of INP104. The droplet size distribution profile was assessed for multiple lots of INP104 using Spraytec technology, confirming that INP104 delivers a consistent spray of large droplets (∼289–735 μm) well outside the respirable range, regardless of the orientation of the device. Comparable droplet size distribution profiles were obtained when the device was stored in either the upright or inverted position. Dx(10), Dx(50), and Dx(90) values denote the size of particles wherein 10%, 50%, or 90% of all particles, respectively, are found.
