P209 Fluticasone propionate and fluticasone/salmeterol multidose dry powder inhalers in patients previously treated through alternative devices

A novel, multidose dry powder inhaler (MDPI) has been developed allowing for lower doses of fluticasone propionate (Fp) and Fp/Salmeterol (FS) compared to previously established metered dose and dry powder inhalers (MDI; DPI). Given the dosing differences, this post-hoc analysis was conducted to evaluate efficacy of Fp and FS MDPI in patients previously treated with Fp and FS MDI/DPI.
