Clinical efficacy of dirithromycin versos miocamycin in the treatment of acute bronchitis or acute exacerbations of chronic bronchitis

A multicentre trial was carried out to compare the efficacy and safety of dirithro-mycin with miocamycin in the treatment of patients with acute bronchitis or acute exacerbations of chronic bronchitis. The study was a single-blind, randomized, parallel-group study. Dirithromycin was administered orally at a dosage of 500 mg once daily and miocamycin was administered orally at a dosage of 600 mg twice daily; the duration of therapy was five to seven days for both drugs. The results, in 161 assessable patients (78 taking dirithromycin; 83 taking miocamycin), show that dirithromycin and miocamycin have comparable efficacy and safety in the treatment of bronchitis caused by susceptible bacterial pathogens
