APSD of Nasal Products
Nasal drug products typically produce droplets larger than 10-20 microns, to ensure nasal deposition and minimise deposition within the lungs. However, a proportion of fine droplets in the <10 micron range may also be produced. Deposition of this respirable fraction beyond the nasal tract may be undesirable and must be quantified. Aerodynamic particle sizing with a cascade impactor is a US FDA requirement and is recommended in USP <601> to assess potential deposition beyond the nasal cavity.
Our nasal sprays, nasal powders and nasal aerosol product testing solutions enable better, more informative testing in line with evolving market requirements.

The angle of the impactor can be adjusted to replicate the angle that the nasal powders device may be used at to investigate device performance under representative conditions. The APSD measurement is unaffected by gravimetric forces.

Related Applications
Two factors have been identified as being critical to improving the clinical relevance of DDU testing and APSD measurement: realistic breathing profiles and realistic throat and nasal models.
