Ingredient-specific particle size (ISPS™) based on wide-field Raman Chemical Imaging (RCI) is promising for accurate particle size determination and particle shape characterization to benefit the bioequivalence requirements for NDAs and ANDAs submissions for aqueous nasal spray suspension formulations. ISPS method was tested on NIST-traceable size standards. Calibration model was built and applied to a commercial nasal spray. Automated data acquisition and image processing produced objective, accurate
drug particle sizes with sufficient representative sampling required for product quality assessment.
