    Abstract:
    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. No statistically significant post-therapy differences in clinical or bacteriological response rates were noted between the two groups. Adverse event analysis showed no significant differences between treatment groups. There were no serious adverse events during the study. Two miocamycin-treated patients were prematurely withdrawn from the study due to adverse events (diarrhoea). Analysis of clinical laboratory data revealed no statistically significant differences between the treatment groups that were considered to be drug related. The results of this study suggest that dirithromycin has comparable safety and efficacy to miocamycin in the treatment of streptococcal pharyngitis/tonsillitis infections caused by Group A streptococci.
