Development of bi-component generic orally inhaled product (OIP) delivered from dry powder inhaler (DPI) is challenging due to the necessity to demonstrate the similarity of size distribution of both APIs in inhaled aerosol. The effects of selected technical factors on OIP development are investigated. The Monodose inhalers with different aerodynamic resistance were used to aerosolize generic fluticasone/salmeterol formulations. Flow dynamics in the DPIs was analyzed during realistic use. The...
