Pefloxacin (400 mg twice daily) was administered orally for infection prophylaxis in neutropenic patients. Diffusible fecal pefloxacin concentration was determined by bioassay during 24 neutropenic periods. The median diffusible fecal pefloxacin concentration was 187 micrograms/g. This concentration was comparable with those found in volunteers following oral and intravenous administration of pefloxacin (400 mg twice daily) (median of 171 and 155 micrograms/g, respectively). From this study, it is concluded that pefloxacin administered orally results in a predictable high diffusible fecal concentration which leads to effective elimination of susceptible aerobic gram-negative bacilli from the colonic flora.
