Comparison of the efficacy, safety and acceptability of cefixime and amoxicillin/clavulanate in acute otitis media.
BACKGROUND
Use of a beta-lactamase stable antibiotic is called for in cases of acute otitis media (AOM) likely to be caused by beta-lactamase-producing Haemophilus influenzae or Moraxella catarrhalis. Two beta-lactamase-stable agents commonly used for empirical treatment of AOM are amoxicillin/clavulanate and cefixime.


METHODS
A multicenter, randomized clinical trial compared cefixime (CFX; 8 mg/kg once daily) with amoxicillin/clavulanate (A/C; 40 mg/kg/day in three divided doses) for the treatment of children with AOM. Three hundred thirteen children were randomly assigned to a 10-day course of either CFX (n = 158) or A/C (n = 155). Based on history, physical examinations and otoscopic and tympanometric assessments, clinical responses were evaluated as cure, improvement, failure, relapse or nonevaluable. Compliance and patient/parent acceptability were also analyzed.


RESULTS
Overall favorable clinical responses (cure plus improvement) were comparable post-therapy for the two treatments (CFX = 76%; A/C = 77%). Significant differences in response rates for both treatments were noted among different geographic regions, with the highest response rates observed in the Northeast and South. Acceptability of CFX was significantly better than that of A/C (P = 0.0001), and the adverse experience rate was lower (P = 0.001). The most frequently reported adverse experiences were diarrhea (CFX 15.2%, A/C 29.7%) and vomiting (CFX 3.2%, A/C 10.32%). Relapse rates were 26% for CFX and 29% for A/C.


CONCLUSIONS
This study demonstrated that CFX has comparable clinical efficacy and a better adverse events profile than A/C when used to treat AOM of childhood.
