Gateway Analytical has teamed up with researchers from the Division of Pharmaceutical Analysis at FDA/CDER to present new findings on temperature-mediated agglomeration assessment in Orally Inhaled and Nasal Drug Products. This study was performed to address aqueous nasal spray suspensions stability during long-term shipping/storage. During the study, suspension formulations were subjected to temperatures that may possibly be reached inside shipping containers during hottest and coldest months in St. Louis, MO.
In 2004, the FDA launched the Critical Path Initiative as a national strategy to drive innovation in development, evaluation and manufacturing of medical products1. As part of this initiative, the FDA identified a number of Critical Path Opportunities (CPOs) for generic drugs. Namely the CPO for Bioequivalence of Nasal Sprays, which identifies a need for direct measurement of particle size equivalence in suspension nasal sprays2.
