Purpose : To evaluate the penetration capability of Levofloxacin and Ciprofloxacin into
prostatic tissue, we analysed the concentration of each drug in serum and prostatic
tissue simultaneously after oral administration.
Materials and Methods : Eleven patients with benign prostatic hyperplasia treated with
transurethral resection of the prostate were entered in this study. A single dose of
200mg Levofloxacin(LVFX) and 250mg ciprofloxacin(CPFX) were administered orally.
Two hours after administration, blood and prostatic tissue samples were taken during
operation. Concentration of each drug in serum and prostatic tissue was measured
simultaneously by high performance liquid chromatography.
Results : The mean concentration of LVFX in serum was 1.970¡¾0.759§¶/ml, which was
significantly higher than that of CPFX(0.903¡¾0.291§¶/m1)(p<0.05). The mean
concentration of LVFX in prostatic tissue(2.256¡¾1.121§¶/g), however, was not
significantly different from that of CPFX(2.395¡¾0.846§¶/g). And the concentration
ratio(tissue/serum concentration) of LVFX and CPFX was 1.16 and 2.76, respectively.
Conclusions : These results show that LVFX is not superior to CPFX with respect to
the penetration capability into prostatic tissue. Considering that the concentration of
LVFX in prostatic tissue was higher than that in serum and not different from that of
CPH, LVFX may be another potential effective agent in treating patients with chronic
bacterial prostatitis.
