This randomized, multicenter study compared the safety and efficacy of cefadroxil with that of cephalexin for the treatment of pyodermas in children and adolescents (1-18 years of age). Cefadroxil was given as a single oral daily dose of 30 mg/kg, and cephalexin 30 mg/kg/day was given in two divided doses. The maximum daily dose for both drugs was 1 gm, and treatment was administered for 10 days. Clinical and bacteriologic evaluations were made on days 4 or 5 during therapy and 2 to 4 days after therapy was completed. Of the 462 patients enrolled in the study, 156 patients in the cefadroxil group and 133 patients in the cephalexin group were evaluable. Staphylococcus aureus (56% of isolates) and Streptococcus pyogenes (39% of isolates) were isolated most frequently. The bacteriologic response was statistically greater in the patients treated with cefadroxil than in those treated with cephalexin (96% versus 89%; P = 0.042). A satisfactory clinical response was reported in 147 (94%) cefadroxil-treated patients and 122 (92%) cephalexin-treated patients (P = 0.476). The overall effective response to treatment was significantly higher with cefadroxil than with cephalexin (94% versus 86%; P = 0.024). Compliance with 9 or 10 days of therapy was similar in both treatment groups, although there was a difference between the two treatment groups with respect to completion of medication regimen: 95% of patients taking cefadroxil once daily-versus 65% of patients taking cephalexin twice daily-took 100% of their medication (P < 0.0001). Adverse events were infrequent and mild. The results of this study demonstrate that once-daily cefadroxil offers greater bacteriologic eradication and a better overall effective response than twice-daily cephalexin for the treatment of pyodermas caused by gram-positive pathogens in children and adolescents.
