Amoxicillin Remains Effective for Treating Acute Otitis Media in Children

The key findings of the study were:

• In a study involving 205 children diagnosed with acute otitis media (AOM) and treated with amoxicillin, researchers found that treatment failure with the antibiotic occurred in 5.4% of cases.

• Recurrence of AOM was observed in 6.8% of children.

• By the fifth day of treatment, 74.1% of participants experienced symptom improvement, while 47.3% achieved symptom resolution.

• Adverse drug events were reported by parents for 27.3% of children.

• Common bacterial otopathogens identified included M. catarrhalis (53.0%), S. pneumoniae (34.2%), H. influenzae (20.1%), and S. aureus (14.1%).

• Interestingly, among children who had not previously received amoxicillin treatment, 65.8% tested positive for beta-lactamase-producing bacteria.

• However, treatment failure rates did not differ significantly between children with and without beta-lactamase-producing otopathogens.

Despite concerns about the increasing prevalence of beta-lactamase-producing bacteria, this study found that treatment failure with amoxicillin for AOM in children was uncommon and did not vary based on the infecting pathogen or beta-lactamase production. These findings support current guidance recommending amoxicillin as the preferred treatment for AOM in children, highlighting its continued efficacy in the face of evolving bacterial resistance patterns.
