[Study on the concentration of cefminox sodium in serum and prostatic tissue].

The concentration of cefminox sodium (CMNX) in serum and prostatic tissue was determined in 25 patients with benign prostatic hypertrophy. One gram of CMNX was intravenously administered prior to transurethral prostatectomy. Blood and prostatic tissue were obtained 1 hour after the administration of CMNX. The concentration of CMNX was 69.17 +/- 17.47 micrograms/ml (mean +/- SD) in serum and 5.33 +/- 2.33 micrograms/g (mean +/- SD) in the prostatic tissue. The ratio of the prostatic tissue concentration/serum concentration was 8.18 +/- 4.45% (mean +/- SD). There was no correlation between serum and prostatic tissue level of CMNX.
