title: [A study on transfer of ceftizoxime into prostatic and vesical tissues].
abstract: Prostatic and vesical tissue levels of Ceftizoxime (CZX) were determined in 21 patients with prostatic hyperplasia after the intravenous administration of 1 g of CZX. Serum concentration on prostatic surgery continued to be 1.3 fold higher than that of healthy adults. Prostatic tissue levels attained a peak of 40.7 +/- 1.6 micrograms/g (mean +/- SE) at 30 minutes after administration and vesical tissue levels attained a peak of 72.4 +/- 24.8 micrograms/g at 30 minutes. The mean value was 21.0 +/- 6.4 micrograms/g in prostatic tissue after administration for 120 minutes with the tissue/serum ratio of 0.91. Prostatic tissue level in glandular dominant were slightly higher than those of myoglandular hyperplasia (P less than 0.1). Judging from its favorable transfer into the prostatic tissue and MIC against clinically isolated E. coli, Proteus sp. and Klebsiella, CZX seemed to be clinically useful in the treatment of prostatic infection.
