Nine centers in Italy participated in a worldwide, multicenter study comparing the effectiveness and safety of lomefloxacin and amoxicillin in patients with acute exacerbations of chronic bronchitis caused mainly by gram-negative pathogens. The 157 enrolled patients received either 400 mg lomefloxacin once daily (n = 78) or 500 mg amoxicillin every 8 hours (n = 79) for 7-10 days. A total of 131 patients were evaluable for bacteriologic efficacy and 154 for clinical efficacy. At 2-4 days after the conclusion of treatment, the bacterial eradication rate was 84.8% for lomefloxacin-treated patients and 64.6% for amoxicillin-treated patients (p = 0.0065); the clinical success rate (cure plus improvement) for lomefloxacin was 94.7% and for amoxicillin was 83.3% (p = 0.0212). The reinfection rate was lower in the lomefloxacin group than in the amoxicillin group (3.0% vs 13.8%, p = 0.0382). Both drug regimens were well tolerated. Once-a-day treatment with 400 mg lomefloxacin was more effective than 500 mg amoxicillin three times daily for the treatment of acute exacerbations of chronic bronchitis caused by gram-negative pathogens.

Abstract
Nine centers in Italy participated in a worldwide, multicenter study comparing the effectiveness and safety of lomefloxacin and amoxicillin in patients with acute exacerbations of chronic bronchitis caused mainly by gram-negative pathogens. The 157 enrolled patients received either 400 mg lomefloxacin once daily (n = 78) or 500 mg amoxicillin every 8 hours (n = 79) for 7-10 days. A total of 131 patients were evaluable for bacteriologic efficacy and 154 for clinical efficacy. At 2-4 days after the conclusion of treatment, the bacterial eradication rate was 84.8% for lomefloxacin-treated patients and 64.6% for amoxicillin-treated patients (p = 0.0065); the clinical success rate (cure plus improvement) for lomefloxacin was 94.7% and for amoxicillin was 83.3% (p = 0.0212). The reinfection rate was lower in the lomefloxacin group than in the amoxicillin group (3.0% vs 13.8%, p = 0.0382). Both drug regimens were well tolerated. Once-a-day treatment with 400 mg lomefloxacin was more effective than 500 mg amoxicillin three times daily for the treatment of acute exacerbations of chronic bronchitis caused by gram-negative pathogens.
