Relative nephrotoxicity of cephalosporin antibiotics in an animal model.
An animal model is described in which mild transitory renal impairment is induced with glycerol and the nephrotoxic effects of cephalosporin antibiotics and furosemide studied. Cephaloridine and cephalothin were found to produce extensive acute tubular necrosis in rats when given in subnephrotoxic doses in combination with furosemide; this damage occurred at serum antibiotic levels not much higher than those obtained in clinical practice. No significant renal damage was found with cephalexin or Cephapirin given in equivalent dosage. It is suggested that the cephalosporin antibiotics should be used with caution in the presence of even minor transient renal impairment and particularly if furosemide is being given concurrently.
