Comparison of the efficacy of ciclesonide with that of budesonide in mild to moderate asthma patients after step-down therapy: a randomised parallel-group study.
Ontology highlight
ABSTRACT: Inhaled corticosteroids (ICSs) are widely used in asthma control. Ciclesonide (CIC) is an ICS with on-site lung activation for potent anti-inflammatory activity.This study aimed to compare the clinical benefit of CIC with budesonide (BUD) in step-down therapy.A total of 150 patients with mild-to-moderate asthma well controlled by a combination of ICS and long-acting β2-agonist were randomised to receive either CIC 320 μg (n=75) once daily or 2 inhalations of BUD 200 μg (n=75) twice daily for 12 weeks. The forced expiratory volume in 1s (FEV1), maximum mid-expiratory flow (MMEF) and asthma control test (ACT) scores were measured. Ranked stratification of patients and physicians was assessed.Drug adherence was significantly higher in the CIC group than in the BUD group (76.0% vs. 58.7%, P=0.03). The FEV1 and MMEF remained stable throughout the 12-week CIC treatment. In the BUD group, FEV1 significantly decreased at weeks 4 and 12. MMEF had a higher value in the CIC group than in the BUD group. Both patients and physicians ranked CIC over BUD.CIC is more effective and has better drug adherence than BUD as step-down treatment when asthma is well controlled by combination therapy.
