Abstrakt: The present study was carried out to investigate disposition kinetics of moxifloxacin following single-dose intravenous (i.v.), intramuscular (i.m.), and subcutaneous (s.c.) administration at a dose rate of 5 mg/kg of body weight (b.wt.) in goats. Plasma samples collected after treatments were analyzed for drug concentration using high-performance liquid chromatography (HPLC). After i.v. administration, distribution of the drug was rapid and wide as reflected by high steady-state volume of distribution. Drug elimination was relatively faster with a total body clearance of 0.59 ± 0.03 L/h/kg. Following i.m. injection, the drug has shown the rapid and near-to-complete absorption with bioavailability of 98.20 ± 3.96 per cent. The maximum plasma drug concentration (Cmax) of 1.21 ± 0.04 μg/mL was attained at 1 h (Tmax). The drug was widely distributed as reflected by high apparent volume of distribution. The elimination half-life (t 1/2β ) of the drug was 6.26 ± 0.08  h. Following s.c. administration, the drug was rapidly absorbed (Cmax: 1.16 ± 0.02 μg/mL; tmax: 1 h) and slowly eliminated from the body. The elimination half-life and total body clearance (ClB) were 5.61 ± 0.10 h and 0.60 ± 0.03 L/h/kg, respectively. The bioavailability of moxifloxacin following s.c. administration was 90.44 ± 3.96 per cent.
