ABSTRACT
The antibacterial activity of cefpirome (CPR), a new parenteral cephalosporin antibiotic having a cyclopentenopyridine group in the 3-position side chain, was evaluated against Neisseria gonorrhoeae and concentrations in human kidney and prostate was determined. The minimum inhibitory concentrations (MICs) of CPR against N. gonorrhoeae isolated clinically in our out-clinic (34 strains of non-PPNG and 20 of PPNG) were less than or equal to 0.003-0.1 microgram/ml in non-PPNG group and 0.006-0.1 microgram/ml in PPNG group. The 90% of MICs (MIC90s) was 0.1 microgram/ml in the non-PPNG group and 0.05 microgram/ml in the PPNG group. The concentration in the prostate was determined in 30 cases with benign prostatic hypertrophy. The maximum values was 52.8 micrograms/g at 15 minutes after administration of 1 g of CPR. The levels of CPR were gradually decreased with the lapse of time. The prostatic tissue concentration was 17.9 micrograms/g at 60 min., 10.1 micrograms/g at 180 min., 7.22 micrograms/g at 320 min. and 2.70 micrograms/g at 360 min. There was a positive correlation between concentration of the prostate and plasma collected at the time of the prostate. The concentration of CPR in human kidney, 90-100 min. after administration of 1 g to 4 cases with renal tumor, was 107-148 micrograms/g in the renal cortex, and 80.6-88.6 micrograms/g in the renal medulla. The concentration in kidney was higher than that in the plasma in all cases. In conclusion, CPR is suggested to be a useful drug for urological infection.
