Abstract

Asthma guidelines recommend titrating maintenance medications to the lowest effective dose. This study assessed the efficacy and tolerability of reducing the frequency of dosing in patients previously controlled with twice-daily budesonide/formoterol (BUD/FM) pressurized metered-dose inhaler (pMDI) to once-daily regimens of BUD/FM pMDI or BUD pMDI. This was a 12-week, randomized, double-blind, double-dummy, placebo (PBO)/active-controlled, multicenter study (N = 752) of patients aged ≥16 years with mild to moderate asthma. After 4-5 weeks on single-blind BUD/FM pMDI 160/9 micrograms twice daily (320/18 micrograms daily), patients with stable asthma received BUD/FM pMDI 160/9 micrograms twice daily (320/18 micrograms daily; morning and evening), BUD/FM pMDI 320/9 micrograms once daily (evening), BUD/FM pMDI 160/9 micrograms once daily (evening), BUD pMDI 320 micrograms once daily (evening), or PBO. BUD/FM (once or twice daily) was more effective (p ≤ 0.003) than BUD and PBO on evening peak expiratory flow (primary variable), morning pulmonary function assessments, daily symptoms, and nighttime rescue medication use. Twice-daily BUD/FM was more effective (p ≤ 0.05) than both once-daily doses for evening pulmonary function assessments and daytime rescue medication use. All treatments were well tolerated. Once- or twice-daily BUD/FM showed better efficacy than BUD once daily or PBO; results generally were more favorable with twice-daily dosing compared with both once-daily dosing regimens, which had one-half the daily FM dose.
