Abstract

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). A total of 575 patients, all with clear signs of AECB, were treated, 292 with moxifloxacin and 283 with co-amoxiclav. Of these, 512 patients were evaluable for efficacy (261 in the moxifloxacin group and 251 in the co-amoxiclav group). The primary efficacy parameter was clinical response at 14 days in the evaluable population. A clinical success was classified as resolution or improvement of symptoms. Variables used to assess clinical response included wheeze, cough, dyspnoea, sputum volume, rales and rhonchi. The success rate for moxifloxacin in the evaluable patients was 96.2% and that for co-amoxiclav was 91.6%. The 95% confidence intervals for this difference (0.4%; 8.7%) indicate equivalence in the treatments. Sputum samples were taken from patients and 140 of these contained a pathogen, Haemophilus influenzae being the most frequently isolated. Moraxella catarrhalis and Streptococcus pneumoniae were also commonly isolated pathogens. The eradication rate at 14 days in the evaluable patients was…

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: 575 participants or records.
