The potential of the force control agent (FCA) magnesium stearate (MgSt) to enhance the aerosol performance of lactose-based dry powder inhaled (DPI) formulations was investigated in this study. The excipient blends were investigated with analytical techniques including time-of-flight secondary ion mass spectrometry (ToF-SIMS) and Single Particle Aerosol Mass Spectrometry (SPAMS) and particle size, morphology and surface properties were evaluated.
