The pharmacokinetics of DWP20364 (1-cyclopropyl -5-amino-6,8-difluoro-7-(2,7-diazabiclo [3,3,0] oct-4-ene-7-yl)-1,4-dihydro-4-oxoquinoline-3-carboxylic acid), a novel fluoroquinolone containing C7-bicyc-talc structure, were compared with those of ciprofloxacin (CPFX) after single intravenous (i.v.) and oral (p.o.) administration to rats using microbiological assay (bioassay). After i.v. administration to rats, the plasma concentrations of the two drugs declined biexponentially. The terminal half-lives (t$_{1}$2$\beta$/) of DWP20364 were 110$\pm$ 13.2 min and 117$\pm$3.09 min after i.v. and p.o. administration, respectively, and they were significantly higher than those of CPFX (45.5$\pm$9.52 min and 48.3$\pm$ 12.1 min, respectively). Similar results were also obtained from plasma concentrations and area under the plasma concentration-time curves. The total body clearance of DWP20364, 7.82$\pm$0.37 ml/min/kg was significantly slower than that of CPFX, 27.3 $\pm$ 11.1 m1/ min/kg. Above data suggested that the antimicrobial activity of DWP20364 could be longer than that of CPFX. The urinary recovery after i.v. and p.o. administration of DWP20364 was significantly lower than those of CPFX suggesting that the effect of DWP20364 on urinary tract infection could be lower than that of CPFX. The serum protein binding values of DWP20364 at 2$\mu$g/ml were apparently 91.5~93.1% in rats and human. DWP20364 was distributed by the order of liver, lung, kidney, sf)leon, heart, muscle and brain collected at 30 min after orally administered.
