In this application note you will learn about establishing an effective test set-up for delivered dose uniformity (DDU) testing of nasal drug products. The note examines compendial requirements for nasal sprays and powders and presents experimental data evaluating the performance of Copley’s Nasal Spray Dose Collector (NSDC) across solution, suspension and powder formulations. It also compares the NSDC with alternative dose collection devices, highlighting its ability to deliver high dose recovery and support reliable, repeatable testing with minimal manual input when used with automated actuation platforms.
