Tissue levels of ofloxacin in the urogenital system

The authors evaluated the tissue levels of ofloxacin in 63 patients with urogenital diseases, in comparison to the minimum inhibitory concentrations 80% (MIC80) of some strains. The drug was administered in a single dose (300 mg) about 3 hours before surgery. After washing carefully, the tissue-levels were measured by using the HPLC method. In the normal renal parenchyma of 8 patients, the mean value was 22.10 micrograms/g of tissue; 19.23 micrograms/g in 13 patients with deranged excretory pathways; 10.62 micrograms/g in 25 patients with benign prostatic hypertrophy; 10.90 micrograms/g in 14 deferent duct patients. These results indicate that the drug is promptly distributed in various tissues of the urinary-genital apparatus at high concentrations.
