<unk>  600 mg achieves peak plasma concentration (Cmax) of ulifloxacin (1.6μg/mL) in a median time to Cmax (tmax) of 1 hour. Ulifloxacin is ≈45% bound to serum proteins in vivo. It is extensively distributed throughout tissues and shows good penetration into many body tissues. The elimination half-life (t1/2) of ulifloxacin after single-dose<unk>  300–600 mg ranged from 10.6 to 12.1 hours. After absorption from the gastrointestinal tract,<unk>  undergoes extensive first-pass metabolism (hydrolysis by esterases, mainly paraoxonase to form ulifloxacin, the active metabolite). Unchanged ulifloxacin is predominantly eliminated by renal excretion. Quoting from the available package insert.
