Amoxicillin twice daily in the treatment of acute otitis media in infants and children.
A total of 110 children with acute otitis media were assigned randomly to treatment with 60 mg/kg per day amoxicillin in a twice-daily (group A) or a thrice-daily (group B) regimen for 10 days. Patients were scheduled for follow-up examinations at mid-treatment, 5 days after the end of therapy and 30, 60, 90 days after starting therapy. At 15 days 6 out of 55 patients (10.9%) treated with amoxicillin twice daily were considered treatment failures compared to 4 children (7.2%) in the thrice daily group. Rates of cure, recurrent otitis media and persistent middle ear effusion were comparable in the two groups of patients at later time intervals. By 90 days the total cure rate was 42.3% (22/52) in children treated twice daily and 41.5% (22/53) in those who had received amoxicillin thrice daily. At the same time persistence of bilateral and unilateral effusion was noted in 12/52 (23.1%) and 8/52 (15.3%) children in group A and in 16/53 (30.1%) and in 10/53 (18.9%) in group B respectively. No significant difference was noted in the two treatment regimens with regard to adverse side effects. Because reduction in division of the amoxicillin dose caused no significant difference in the efficacy of antibiotic treatment of acute otitis media in infants and children, we think that this simplified scheme of therapy can routinely be used in clinical practice and thus improve compliance to antibiotic administration.
