Pharmacokinetic study on adenomatous prostate tissue concentrations of cefoperazone. Clinical efficacy and patient tolerance of intramuscular cefoperazone treatment of chronic bacterial prostatitis.
Cephalosporins do not reach active therapeutical concentrations in the prostatic tissue in patients suffering from chronic bacterial prostatitis. Cefoperazone is an exception. Its efficacy in the treatment of chronic bacterial prostatitis in 20 patients was studied and the concentrations, obtained after intramuscular administration, evaluated in patients who underwent transurethral operation due to prostatic hypertrophy (in 14 patients). The cefoperazone concentrations in the prostate have been evaluated 60, 90 and in some cases 120 min after the administration of the drug and compared to those obtained in serum. The clinical cure has been obtained in 16 patients. The average drug concentration in the prostate after 60 min was 22.8 +/- 13.6 versus 39.8 +/- 20.0 micrograms/ml in serum; 90 min after administration the average concentration in the prostate was 23.2 +/- 14.1 versus 35.7 +/- 18.1 micrograms/ml in serum. The correlation was significant both at 60 min (r = 64, p less than 0.05) and at 90 min (r = 64, p less than 0.05).
