Pharmacokinetics and urinary excretion of an intravenous dose of 5 mg.kg-1 ofloxacin were investigated in water buffalo calves. Plasma concentrations of ofloxacin were determined by high-performance liquid chromatography. Ofloxacin was rapidly distributed from the central to the peripheral compartment as evidenced by a short distribution half-life (0.09 h ± 0.003 h) and high K12 (4.7 h(-1) ± 0.1 h(-1)), and was detected in plasma for 8 h. The large volume of distribution (2.48 L.kg(-1) ± 0.18 L.kg(-1)) obtained in this study indicated high distribution of ofloxacin in water buffalo calves. The elimination half-life, the area under the plasma drug concentration-time curve and total body clearance were 2.11 h ± 0.13 h, 6.20 µg.mL(-1) ± 0.23 µg.mL(-1).h and 0.81 mL.kg(-1).h(-1) ± 0.03 mL.kg(-1).h(-1), respectively. About 18.7% of administered drug was bound to plasma proteins and approximately 32.5% of the administered dose was recovered in urine within 48 h. The results of the study indicated a favourable pharmacokinetic profile of ofloxacin in water buffalo calves, which suggests that ofloxacin may be effective against urinary pathogens in this species. |
