A Study of the Safety and Effectiveness of Oral Levofloxacin Compared With Cefuroxime Axetil in the Treatment of Adults With Persistent Bronchitis Experiencing Rapid Onset of Severe Worsening of Symptoms Caused by Bacteria
- Conditions
- Bronchitis, Chronic
- Registration Number
- NCT00269932
- Brief Summary
The purpose of this study is to evaluate the safety and effectiveness of levofloxacin, an antibiotic, compared with cefuroxime axetil, another antibiotic, in the treatment of adults with chronic bronchitis experiencing rapid onset of worsening of symptoms caused by bacteria.
- Detailed Description
This is a randomized, open-label, parallel group, multicenter study to determine the safety and effectiveness of 500 mg of levofloxacin (once daily for 5 - 7 days) compared with 250 mg of cefuroxime axetil (every 12 hours for 10 days) in adults with chronic bronchitis experiencing rapid onset of severe worsening of symptoms caused by bacteria. The study consists of 3 visits: one visit for screening and enrollment, and 2 visits for assessment of safety and effectiveness (one visit on Days 3 - 5 of the study and one visit \[post-therapy\] 5 - 7 days after the last dose of the study drug). The total duration of patient participation in the study is approximately 2 weeks. The primary efficacy assessment is the clinical response 5 - 7 days after the last dose of study drug, (categorized as cured, improved, or failed) based upon changes in signs and symptoms. Safety evaluations (incidence of adverse events, physical examination, laboratory tests) are performed throughout the study. The study hypothesis is that treatment with levofloxacin is at least as effective and as well tolerated as treatment with cefuroxime axetil in adult patients with chronic bronchitis experiencing sudden worsening of symptoms caused by bacterial infection. Levofloxacin 500 mg by mouth once daily for 5 - 7 days, or cefuroxime axetil 250 mg by mouth every 12 hours for 10 days
