Successful development of generic nasal drug products requires sponsors to understand how the dose is atomized by the chosen pump device in order to achieve bioequivalence. In addition, the impact of atomization of the particle size of the drug substance must also be determined in the case of suspension-based products. In this webinar, we introduce how laser diffraction droplet size analysis and Morphologically Directed Raman Spectroscopy (MDRS) can be applied to gain this insight, significantly speeding up the development of new generic formulations.
