Loracarbef versus clarithromycin in children with acute otitis media with effusion

Two multicenter, randomized, single-masked, parallel-group studies compared loracarbef and clarithromycin with regard to efficacy, tolerability, and patient acceptance. Three hundred thirty-four children aged 6 months to 3 years with acute otitis media with effusion received loracarbef (15 mg/kg) or clarithromycin (7.5 mg/kg) orally twice daily for 10 days. Patients were assessed for the presence of the diagnostic signs and symptoms of otitis media with effusion by physical examination and pneumatic otoscopy at 48 hours pretreatment, 3 to 5 days after initiation of treatment, 0 to 3 days after the final dose (posttreatment), and 14 to 21 days later (termination). Symptoms were assigned numeric values. Symptomatic response was assessed at the posttherapy and termination visits. Tolerability was determined by assessing adverse events, and a patient acceptance survey was completed by each patient's caregiver. The combined results of these 2 studies showed that the efficacy and tolerability of loracarbef were comparable to those of clarithromycin. Adverse events were reported by 46.4% of loracarbef patients and 41.0% of clarithromycin patients, with no statistically significant difference between groups. In the intent-to-treat analysis, 57.9% of loracarbef patients were cured at the termination of the study, compared with 55.7% of clarithromycin patients. Improvement was seen in 4.1% of loracarbef patients and 2.7% of clarithromycin patients. Results of the patient acceptance survey showed a clear preference for loracarbef over clarithromycin. Difficulties with administration of treatment were reported by 36.3% of clarithromycin caregivers, compared with 7.8% of loracarbef caregivers (P < 0.001). A desire to stop treatment was reported by 23.8% of clarithromycin caregivers, compared with 7.8% of loracarbef caregivers (P < 0.001). Taste and texture issues were most frequently cited as reasons for nonacceptance.
