Objective. Compare the effectiveness and tolerability of the cefadroxil vs oxacillin in the treatment of the skin infections and soft tissue. Population and Methods. We carried out a randomized controlled study, in single blind fashion, of groups in parallel. A total of 64 patients were divided at random in two groups to receive cefadroxil (31 patients) or oxacillin (33 patients). It was carried out a basal clinical exam that included local evaluation of the lesion with inflammation scale of 15 points, besides basal temperature and white cell count. We repeat this evaluation at 48 hours, at the 4th day and day 10. In the comparision of effectiveness we were considered the parameters of clinical cure, clinical improvement and therapeutic failure, the modification on inflammation scale, temperature and cell count were also analyzed. Results The obtained data demonstrated that it was proven definitive cure in 87% of the cases with cefadroxil that was similar to the group treated with oxacillin (78,8%). The therapeutic failure was 12% with cefadroxil and 21% with oxacillin. The results of the intragrupal comparison on day 0 vs day 2, and day 0 vs day 4, demonstrated a significant reduction in the inflammation scales, so much in the patients treated with cefadroxil and oxacillin. Both treatments achieved a significant clinical improvement of the inflammatory scale on days 5 to 6, allowing the step of the treatment from parenteral to route oral, in that period. The definitive cure was achieved in an average of 8 days. There were not significant differences in the time of descent of the basal temperature. As for the white counts, it could be proven a remarkable descent and sustained in both groups of treatmet, reaching statistical significance in days 2 and 4. Only two patients in each group were removed by adverse effects (cefadroxil 6.45% and oxacillin 6.06%) Conclusions. We concluded that the cefadroxil has a superior therapeutic effectiveness against oxacillin in the treatment of slight to moderate infections of skin and soft tissue, oxacillin showed a higher percentage of therapeutic failure and both were safe drugs in the treatment of this infections, showing a low proportion of adverse effects.
