Area of Science:

  • Pharmacology
  • Urology
  • Infectious Diseases

Background:

  • Bacterial prostatitis and postoperative prostate infections pose significant clinical challenges.
  • Effective antibiotic penetration into prostatic tissue is crucial for successful treatment.

Purpose of the Study:

  • To determine the concentration of Cefbuperazone (CBPZ) in prostatic tissue and serum.
  • To evaluate the efficacy of CBPZ against common pathogens in the prostate.

Main Methods:

  • Intravenous administration of 1g or 2g of CBPZ to 23 patients undergoing transurethral prostatectomy.
  • Measurement of CBPZ levels in prostatic tissue and serum at 1 hour post-injection.
  • Correlation analysis between tissue CBPZ levels, dosage, and prostatic tissue weight.

Main Results:

  • Mean prostatic tissue CBPZ levels were 17.4 µg/g (1g dose) and 34.7 µg/g (2g dose) at 1 hour.
  • Tissue-to-serum ratios indicated good drug penetration.
  • Prostatic tissue CBPZ levels exceeded the minimum inhibitory concentration (MIC80) for key pathogens like E. coli.

Conclusions:

  • Cefbuperazone achieves sufficient concentrations in prostatic tissue to inhibit bacterial growth.
  • CBPZ is a potentially valuable therapeutic agent for bacterial prostatitis and preventing postoperative prostate infections.
