Comparison of cefuroxime axetil and amoxicillin-clavulanate suspensions in treatment of acute otitis media with effusion in children

Abstract

Two hundred sixty-three pediatric patients from the ages of 3 months to 11 years were enrolled in a randomized, investigator-blinded, multicenter study comparing the clinical and bacteriological efficacies and safety of cefuroxime axetil suspension (CAE) with those of amoxicillin-clavulanate suspension (AMX-CL) in the treatment of acute otitis media with effusion. Patients received CAE at 30 mg/kg of body weight per day (n = 165) in two divided doses or AMX-CL at 40 mg/kg/day (n = 98) in three divided doses for 10 days. The primary pathogens among 200 isolates from pretreatment cultures of middle ear fluid were identified as follows: Haemophilus influenzae (39%), over a third of which were beta-lactamase positive; Streptococcus pneumoniae (34%); and Moraxella catarrhalis (16%). Pathogens were eradicated or presumed to be eradicated from 81% (95 of 118) and 76% (50 of 66) of bacteriologically evaluable patients in the CAE and AMX-CL groups, respectively. A satisfactory clinical response (cure or improvement with or without resolution of effusion) occurred in 113 (77%) of 146 clinically evaluable patients in the CAE group and in 66 (74%) of 89 evaluable patients in the AMX-CL group. Clinical failure or recurrence (within 2 weeks following the completion of treatment) occurred in 22 and 26% of CAE- and AMX-CL-treated patients, respectively. Drug-related adverse events occurred in 18% of CAE-treated patients, whereas they occurred in 39% of AMX-CL-treated patients (P < 0.001); diarrhea or loose stools was the most commonly reported adverse event (CAE, 12%; AMX-CL, 31%; P < 0.001). These results indicate that CAE given twice daily is as effective as AMX-CL given three times daily in the treatment of acute otitis media with effusion in pediatric patients, but CAE was associated with significantly fewer drug-related adverse events.
