[Concentration of cefamandole in human renal parenchyma (author's transl)].

(6R-[6alpha,7beta(R)])-7-[(hydroxyphenylacetyl)amino]-3-([(1-methyl-1H-tetrazol-5-yl)-thio]methyl)-8-oxo-5-thia-1-azabicyclo[4,2,0]oct-2-ene-2-carbonic acid (cefamandole) levels have been determined in human renal tissue, serum, and urine of 17 patients undergoing therapeutic nephrectomies after 3 i.v. applications of 2 g cefamandole. As far as possible levels of renal cortex and renal medulla were investigated separately. The concentrations of the antibiotic in human renal tissues, removed in the interval from 2 h 10 min to 6 h 25 min after last application of the drug, were distinctly above the minimum inhibitory concentrations of most bacterial strains responsible for urinary tract infections and cases of chronic pyelonephritis. Concentrations of the drug were usually lower in renal parenchyma alterated by chronic inflammatory processes than in "normal tissue" of tumor kidneys. With separate determinations of drug levels in the cortical and medullary regions concentrations of the drug were usually higher in the cortical part of the kidney.
