[Cefixime concentration in human prostatic tissue following 3-days of administration].
The penetration of Cefixime (CFIX) into the prostatic tissue and the serum was examined in 54 patients with benign prostatic hypertrophy treated with transurethral resection of the prostate. CFIX was administered orally in a dose of 200 mg 2 times daily for 3 days preoperatively. The blood samples were taken at the time of the tissue sampling. The patients were divided into 2 groups. In group 1 (16 patients), the tissue sampling was done about 17 hours after the final drug administration. The mean concentration of CFIX was 0.83 +/- 0.49 micrograms/g in the prostatic tissue and 0.84 +/- 0.63 micrograms/ml in the serum. In the prostatic tissue, CFIX was detected in only 4 patients, in the other 12 patients, CFIX was not detected. In group 2 (38 patients), tissue sampling was done 5.5 hours after the final drug administration. The mean concentration of CFIX was 1.08 +/- 0.47 micrograms/g in the prostatic tissue and 3.18 +/- 1.28 micrograms/ml in the serum.
