Renal tolerance tests in Wistar rats (n = 40) over 12 days showed that the tubulotoxic threshold dose of the cephalosporin antibiotic (6R,7R)-7-(2-[3,5-dichloro-4-oxo-1(4H)-pyridyl]-acetamido)-3-([(5-methyl-1,3,4-thiadiazol-2-yl)-thio]methyl)-8-oxo-5-thia-1-azabicyclo[4,2,0]oct-2-ene-2-carboxylic acid acid (cefazedone, Refosporen) is 2000 mg/kg/day when the cell excretion rates in the urine are used as the parameter of toxicity. It is concluded that cefazedone and cefazolin are similar in respect of their nephrotoxicity.
