Single intramuscular dose of ceftriaxone as compared to 7-day amoxicillin therapy for acute otitis media in children. A double-blind clinical trial.

Fifty-two children (mean age 23 months) with acute otitis media were treated randomly with either a single intramuscular dose of ceftriaxone (Rocephin) 50 mg/kg (27 patients) or 7 days of amoxicillin 12.5 mg/kg t.i.d. (25 patients). The rate of resolution of acute symptoms and incidence of recurrences and relapses during the first months after commencement of the therapy was similar in the two groups. One week following the start of treatment no difference was observed in the proportion of patients with tympanometric evidence of middle ear effusion (MEE) in either of the two groups. On day 30, however, significantly more patients from the ceftriaxone group had flat tympanograms-83% as compared to 47% in the amoxicillin group. Therefore, single-dose ceftriaxone therapy cannot be suggested at present as routine therapy for acute otitis, although it may be considered a reasonable alternative in noncompliant patients.
