Suspension nasal spray products typically contain an active pharmaceutical ingredient (API) along with other excipients. The ability to obtain API-specific particle size data for these formulations is an important part of production Quality Control. Manual analysis of Light Microscopy images is commonly employed to perform this task. However, separating API particles from excipient particles can be qualitative and subjective. The Morphologi® is a fully automated instrument designed to capture microscope images of dispersed particles and quantitatively analyze them for size and shape. In this application note, we demonstrate how to expedite a QC method for Nasal Spray formulations and ensure consistent analysis of repeated measurements.
