This webinar was designed for generic drug manufacturers of nasal spray suspensions. During this webinar, our presenters discussed how the method of Ingredient-Specific Particle Sizing (ISPS) using Raman Chemical Imaging (RCI) developed by Gateway Analytical, can address the critical path opportunity by providing the accurate and precise drug particle size measurement to demonstrate bioequivalence. Using this method, generic nasal spray suspension developers have the potential to save considerable time and money by waiving the in vivo biostudies.
