Efficacy and safety of azithromycin and amoxicillin/clavulanate for otitis media in children: a systematic review and meta-analysis of randomized controlled trials

Ann Clin Microbiol Antimicrob. 2021 Apr 24;20(1):28. doi: 10.1186/s12941-021-00434-x.

Abstract

Background: Resistance, prolonged therapy, and more adverse reactions made amoxicillin less preferred for treating otitis media. This study aimed to compare the efficacy and safety of azithromycin and amoxicillin/clavulanate for the treatment of otitis media in children.

Methodology: This study was a systematic review and meta-analysis. PubMed, Cochrane library, and Google scholar databases were searched. Comparative randomized clinical trial studies between azithromycin and amoxicillin/clavulanate to treat otitis media in children published up to 30 September 2019 were included. The risk of bias was assessed and Data was extracted by the first author and checked by the second author. Meta-analysis was performed by STATA software version 16, and Mantel-Haenszel statistical method with effect measure odds ratio was employed for analysis.

Result: 751 records were identified and 14 studies were eligible for analysis. In 12 studies azithromycin had equivalent clinical efficacy and 2 had less to amoxicillin/clavulanate. Meta-analysis results showed no statistically significant difference in efficacy in favor of amoxicillin/clavulanate after completion of treatment OR 0.75, 95% CI (0.62-0.91). On subgroup analysis for children less than 2 years (OR 0.96 95% CI (0.49-2.29), and greater than 2 years (OR 1.40 95% CI (0.93-2.11) and also efficacy on follow up (OR 0.97 95% CI (0.83-1.15) there is no statistically significant difference. The clinical adverse events are more in the amoxicillin/clavulanate group than in the azithromycin with a statistical significant difference OR 0.46 95% CI (0.43-0.56).

Conclusion: Azithromycin is comparable to amoxicillin/clavulanate to treat otitis media in children, and it is safer and more tolerable.
