Clinical efficacy of dirithromycin versus miocamycin in tonsillopharyngitis

A single-blind, randomized, parallel-group study was conducted to compare the efficacy and safety of dirithromycin with miocamycin in the treatment of streptococcal pharyngitis/tonsillitis caused by Group A streptococci. The study population consisted of 60 patients: 30 were randomized to receive 500 mg dirithromycin od and 30 to receive 600 mg miocamycin bd. All 30 dirithromycin-treated patients were eligible for efficacy analysis. A favourable clinical response was observed in 100% of these patients at the post-therapy visit. In the miocamycin-treated group, 28 of 30 (93.3%) patients were eligible for efficacy analysis; a favourable clinical response was observed in 100%. Bacteriological cure of evaluable dirithromycin- and miocamycin-treated patients was 96.7% and 92.9%, respectively
