Abstract
Objective: We performed a multicentre study under a 2-year observational protocol that included data on time to recovery from acute exacerbations of chronic obstructive pulmonary disease (AE-COPD) in patients receiving moxifloxacin and comparator antimicrobials.
Patients and methods: Outpatients with moderate or severe COPD were recruited from respiratory clinics throughout Spain. Moxifloxacin was available in year 2, and was to be prescribed to 50% of patients in that period in a non-randomised allocation. Time to recovery was compared in successfully treated AE-COPD; cross-sectionally for all AE-COPD over 2 years, first AE-COPD and all AE-COPD in year 2, and longitudinally in patients receiving comparator antimicrobials for AE-COPD in year 1 and moxifloxacin in year 2.
Results: 614 AE-COPD were treated in 441 patients over 2 years (mean age 66.7 ± 8.3 years, 98% males, mean forced expiratory volume in 1 second [FEV1] 35.9 ± 8.8%). Mean time to recovery overall was 4.6 days (SD 3.3) with moxifloxacin 400 mg/day for 5 days, and 5.8 days (SD 4.6) with comparators (p < 0.01), which were most frequently amoxicillin/clavulanic acid 500/125mg/8h, clarithromycin 500mg/12h and cefuroxime axetil 500mg/12h for 7–10 days. Longitudinal analysis showed that 27 patients treated with moxifloxacin in the second year of the study recovered in a mean of 3.7 days (SD 3.1), and the same patients treated with comparator antimicrobials in year one recovered in a mean of 6.8 days (SD 4.6) [p = 0.02]. In contrast, in 66 patients treated with comparator antimicrobials in both years, mean time to recovery was 7.4 days (SD 7.3) in year one and 5.5 days (SD 3.5) in year two (p = 0.24). All subgroup analyses showed a statistically significant reduction of 18–25% in time to recovery with moxifloxacin compared with other antibiotics.
Conclusions:Moxifloxacin significantly reduced time to recovery from AE-COPD in patients with moderate to severe disease by approximately 20% (>1 day) compared with other antimicrobials. Faster recovery should result in earlier return to work or normal activities, and to social and economic savings.
