A multinational, multicentre, non-blinded, randomized study of moxifloxacin oral tablets compared with co-amoxiclav oral tablets in the treatment of acute exacerbation of chronic bronchitis.

The aim of this study was to compare the efficacy and safety of once daily dosing with moxifloxacin (BAY 12-8039) with that of coamoxiclav given three times daily for the treatment of acute exacerbation of chronic bronchitis (AECB). Moxifloxacin (one 400 mg tablet daily) was administered orally for 5 days and co-amoxiclav (three 625 mg tablets daily) was given orally for 7 days. The study was randomized, non-blinded, multinational (12 countries) and multicentre (68 centres).

Five day moxifloxacin therapy compared with 7 day clarithromycin therapy for the treatment of acute exacerbations of chronic bronchitis.

In this multinational, randomized, double-blind study, the efficacy and safety of a 5 day course of moxifloxacin 400 mg orally od was compared with that of a 7 day course of clarithromycin 500 mg orally bd. in 750 patients with acute exacerbations of chronic bronchitis, characterized by at least two of the symptoms: sputum purulence, increased sputum volume or increased dyspnoea. Seven days after the end of therapy, clinical cure was achieved for 89% (287 of 322) of efficacy-evaluable patients in the moxifloxacin group and 88% (289 of 327) of patients in the clarithromycin group (95% CI, -3.
