A Study of the Effectiveness and Safety of High Dose, Short-course Levofloxacin in the Treatment of Acute Bacterial Exacerbation (Worsening) of Chronic Bronchitis
Abstract
The purpose of this study is to evaluate the safety and effectiveness of four oral antibiotic treatment regimens for bacterial infections in patients with chronic bronchitis. The study goals are to demonstrate that 1) levofloxacin 750 mg once daily for three days is no worse than azithromycin 250 mg twice a day for one day and then 250 mg once a day for four more days, and 2) levofloxacin 750 mg once daily for five days is no worse than amoxicillin/ clavulanate (875/125 mg) twice daily for 10 days.
Conditions: Bronchitis, Chronic Bronchitis.
Primary outcome: Clinical response rates based on signs and symptoms at posttherapy visit..
Enrollment: 659 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 659 participants or records.
