Characterizing A Nasal Spray Formulation From Droplet To API Particle Size

Regulatory guidance for nasal spray products recognises the effect on drug delivery of the particle size of both the delivered droplets and the suspended active. Here we examine the application of laser diffraction and automated image analysis combined with Raman spectroscopy in this context, highlighting the role these techniques can play in fast and efficient nasal spray characterisation.
