Norfloxacin penetration into human renal and prostatic tissues

Abstract

Concurrent norfloxacin concentrations in serum, kidney, and prostatic tissue were determined in 14 patients. Mean ratios of norfloxacin concentration in tissue over concentration in serum were 6.6 +/- 2.8 for the kidney and 1.7 +/- 0.2 for the prostate samples. The levels were above the MICs of most urinary pathogens.
