title: A multicenter, randomized, open label comparison of azithromycin and amoxicillin/clavulanate in acute otitis media among children attending day care or school.
abstract: OBJECTIVE
  This multicenter, randomized, open label study compared the efficacy and safety of azithromycin and amoxicillin/clavulanate for the treatment of acute otitis media among children who were attending a day-care facility or school.
  
  
  METHODS
  Eligible children with acute otitis media from 21 US centers were randomized to treatment with 10 mg/kg of azithromycin oral suspension on Day 1, followed by 5 mg/kg once daily for the next 4 days or approximately 40 mg/kg/day of amoxicillin/clavulanate suspension in 3 divided doses for 10 days. Clinical efficacy was evaluated on Days 14, 30 and 45. Acceptance and convenience of the medications were assessed on Day 14 by parent interviews with a standardized questionnaire.
  
  
  RESULTS
  Of the 263 children enrolled in the study, 233 were evaluable at the primary evaluation 45 days after the start of treatment. Satisfactory clinical response rates (cure, delayed cure and improvement) were 60.5% in patients treated with azithromycin and 64.9% in patients treated with amoxicillin/clavulanate. Satisfactory clinical response rates at secondary evaluations were also comparable: 92.2% vs. 90.0% at Day 14 and 66.7% vs. 72.7% at Day 30 in patients treated with azithromycin and amoxicillin/clavulanate, respectively. No significant differences in treatment failures, relapses or recurrences were noted with either medication. Azithromycin was significantly better tolerated and caused fewer treatment-related adverse events (7.2%) than amoxicillin/clavulanate (17.1%) (P < 0.001). In response to the interview and questionnaire, parents of children treated with azithromycin noted less need for special arrangements to give medication (2.0% vs. 14.9%). Children liked the taste of azithromycin (89.2%) and did not have to be forced to take the medication (2.4%). Parents of children receiving amoxicillin/clavulanate noted that 61.8% liked the medication and 19.4% of children had to be forced to take it.
  
  
  CONCLUSIONS
  This study demonstrates that azithromycin was comparable to amoxicillin/clavulanate in achieving satisfactory clinical response rates in children with acute otitis media attending day care or school. Azithromycin was significantly better tolerated than amoxicillin/ clavulanate. Parents considered azithromycin to be significantly more convenient to administer and more acceptable to children.
