APSD of Nebulisers
For devices such as nebulisers, the evaporation of droplets exacerbated by the thermal mass of the impactor can be a problem, especially for drugs in solution. Loss of solvent reduces droplet size, producing artificially low APSD measurements, compromising the integrity of the resulting data. Cooling the impactor to approximately 5°C is the recommended method for overcoming this problem. The recommended flow rate of 15 L/min employed in the APSD testing of nebulisers is lower than that of other OINDPs in order to better represent the tidal breathing conditions employed in their use.

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.

One of the main factors influencing the amount of inhaled drug available to the patient is the interface between the facemask and the patient. Investigating and defining the effect of a facemask to the product’s DDU and APSD is important for the product development.
