Clinical efficacy of azithromycin in lower respiratory tract infections
Abstract
A total of 51 patients with acute exacerbation of chronic bronchitis and pneumonia were enrolled: 27 treated with azithromycin (500 mg once a day for 3 days), and 24 with roxithromycin (150 mg every 12 hours for 7 days). The two regimens were equally effective, with clinical cure in 80% and 72% of patients respectively. Bacteriological eradication on day 19-23 was obtained in 7/11 cases (64%) and in 6/13 cases (46%) in the two groups, respectively. No side effects occurred in patients treated with azithromycin, while they occurred in the roxithromycin group (2 vomiting and 1 gastritis). Clinical and bacteriological efficacy, excellent tolerability, simplified dosage (single daily dose) and short-course (3 days) therapeutic regimen make azithromycin, in our experience, efficacious for the treatment of acute exacerbation of chronic bronchitis and community-acquired pneumonia.
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: 51 participants or records.
