Patients treated with high dose (1000/100 μg daily) fluticasone/salmeterol (FP/S) either DPI or pMDI entered a 2-month run-in with FP/S Diskus 1000/100 μg daily. Controlled patients (GINA) were treated with either FP/S Diskus 500/100 μg daily or extrafine beclomethasone/formoterol (BDP/F) pMDI 400/24 μg daily for 6 months. Morning PEF was the primary outcome. Secondary outcomes included asthma control.Results: 378 patients were evaluated for ITT; previous treatment was DPI in 87% of patients. Equivalence was shown in morning PEF at the end of treatment (difference between means 2.49 L/min; 95% CI -13.43 to 18.42).Morning PEF remained above 95% predicted throughout the study, though absolute values decreased (414.4 to 397.1 L/min for BDP/F; 429.7 to 394.6 L/min for FP/S; p=0.0001). Asthma control was maintained in the majority of patients with no worsening in FEV1 measured at clinics, symptoms score, use of rescue medication and no differences in any parameter including exacerbations.View this table:Conclusions: Patients controlled with high dose ICS/LABA DPI can be stepped-down to medium dose either DPI or extrafine pMDI mantaining asthma control.
