From actuation to deposition: Particle sizing techniques for characterizing nasal drug delivery systems

The droplet size of nasal sprays is a critical performance parameter because of its influence on deposition behavior. Laser diffraction and cascade impaction dovetail to provide the size data required to aid product development and QC.
