The efficacy of moxifloxacin in acute exacerbations of chronic bronchitis: a Spanish physician and patient experience.

Chronic bronchitis is a debilitating disease affecting many millions of patients globally. They suffer multiple acute exacerbations each year, often requiring many courses of antimicrobials to enable them to return to normal. The impact of the condition on both the individual patient and society as a whole is considerable and growing; thus antimicrobial therapy should induce rapid and effective outcomes as soon as possible. This open, community-based study of 5737 patients enrolled by over 2000 primary care physicians from across Spain examined the clinical effect of oral moxifloxacin on patients' signs and symptoms of acute exacerbations of chronic bronchitis (AECB) over a 45-day period. The symptoms were assessed using daily diary cards in addition to physician evaluations. Clinical assessment at day 7 showed 93.0% of patients were cured. The patient diary card showed that two-thirds of patients felt better by day 3 or 4. Adverse events were reported in 3.5% of patients in this study, the most common being diarrhoea, nausea and dizziness, and epigastric pain. These reactions were mild to moderate in intensity. There were no patient deaths due to infection during the study. Physicians and patients reported that once-daily moxifloxacin gave fast relief of symptoms of acute exacerbations of chronic bronchitis.
