Tuning Aerosol Particle Size Distribution of Metered Dose Inhalers Using Cosolvents and Surfactants
Objectives. The purpose of these studies was to understand the influence of cosolvent and surfactant contributions to particle size distributions emitted from solution metered dose inhalers (pMDIs) based on the propellant HFA 227. Methods. Two sets of formulations were prepared: (a) pMDIs-HFA 227 co...
