A comparative study of the efficacy, safety and tolerability of azithromycin and cefaclor in the treatment of children with acute skin and/or soft tissue infections

An open, multicentre study was carried out in 200 paediatric patients between 6 months and 12 years of age with skin and/or soft tissue infections (mild-to-moderate dermatological conditions and abscesses) to compare the efficacy and safety of azithromycin and cefaclor oral suspensions. Patients were randomly assigned to receive either azithromycin (10 mg/kg once daily for 3 days) or cefaclor (20 mg/kg/day in three divided doses for 10 days). The clinical efficacy of both treatments was comparable: 92/98 (94%) of the evaluable azithromycin patients were cured or improved as were 93/98 (95%) of those treated with cefaclor. Before treatment, 74 pathogens were isolated from 60 of the azithromycin- and 80 pathogens from 66 of the cefaclor-treated patients. In the azithromycin group, 70/74 (95%) pathogens were eradicated, as were 79/80 (99%) pathogens in the cefaclor group. All 200 patients were evaluable for safety analyses. Both drugs were well tolerated, with a low incidence of side-effects: 3/100 (3%) in the azithromycin group and 2/100 (2%) in the cefaclor group. No patient in either treatment group withdrew from the study because of adverse events. In conclusion, azithromycin is as effective and as well tolerated as cefaclor in the treatment of children with skin and/or soft tissue infections.
