PITTSBURGH, Nov. 19, 2010 — Gateway Analytical will be presenting research findings from a validation study that applied NIST-traceable size standards to data obtained from the ingredient-specific particle size analysis, an approach that uses wide-field Raman chemical imaging (RCI) to determine drug-specific particle measurements, of nasal spray samples. Results will be presented, Dec. 8-9 at Drug Delivery to the Lungs 21 (DDL21), Edinburgh International Conference Centre, Edinburgh, United Kingdom.

The study, titled Application of NIST-Traceable Size Standards to Ingredient-Specific Particle Sizing, used Raman chemical images of Rhinocort Aqua® droplets to detect and measure particles of its active ingredient, budesonide. A calibration model was then created utilizing Raman chemical images of NIST-traceable polystyrene microsphere sizing standards and applied to the Rhinocort RCI data, which showed promising results.

In addition to presenting research findings at DDL21, Gateway Analytical will also be exhibiting at booth 37 throughout its duration.  As Europe’s premier conference and exhibition dedicated to pulmonary and nasal drug delivery, DDL21 will feature such topics as methods for investigating in vivo pulmonary drug depositions, ways to increase success of inhaled products early in development and advances in formulation and analytical science.
