Efficacy of gemifloxacin in acute exacerbations of chronic bronchitis: a randomised, double-blind comparison with trovafloxacin
Abstract
This randomised, double-blind, double-dummy, multinational study compared the efficacy and safety of gemifloxacin with trovafloxacin in the treatment of acute exacerbations of chronic bronchitis. There were 617 patients randomised: 303 to gemifloxacin and 314 to trovafloxacin. Clinical success rates at follow-up (clinical per-protocol population) were 91.5% for gemifloxacin and 87.6% for trovafloxacin. For the intent-to-treat population, the clinical efficacy of gemifloxacin was statistically significantly superior to that of trovafloxacin. In general, the in vitro activity of gemifloxacin against the major respiratory bacterial pathogens was superior to that of other antibiotics tested. Per-patient bacteriological success rates at follow-up (bacteriology per-protocol population) were 86.8% for gemifloxacin and 82.4% for trovafloxacin. Both agents were well tolerated. The clinical and bacteriological efficacy of a once-daily 5-day course of gemifloxacin is at least as good as that of a similar regimen of trovafloxacin in the treatment of acute exacerbations of chronic bronchitis.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 617 participants or records.
