Various doses of single, dual and triple combination cosuspensions were produced at small scale with a process representative of commercial scale, and were found to be stable with dose-proportional and uniform aerodynamic size distribution profiles.
The central role of cascade impaction in the analytical toolkit for inhaled products is largely attributable to the fact that, unlike all other particle sizing methods, this one provides a mass-weighted distribution based on aerodynamic size for the active ingredient, rather than for the complete formulation.
