We evaluated the pharmacokinetics of ciprofloxacin in serum (n = 6) and urine (n = 4) in goats following a single intravenous administration of 4 mg/kg body weight. The serum concentration-time curves of ciprofloxacin were best fitted by a two-compartment open model. The drug was detected in goat serum up to 12 h. The elimination rate constant (<FONT FACE="Symbol">b) and elimination half-life (t<SUB>1/2</SUB><FONT FACE="Symbol">b) were 0.446 ± 0.04 h and 1.630 ± 0.17 h, respectively. The apparent volume of distribution at steady state (Vd<SUB>ss</SUB>) was 2.012 ± 0.37 l/kg and the total body clearance (Cl<SUB>B</SUB>) was 16.27 ± 1.87 ml/min/kg. Urinary recovery of ciprofloxacin was 29.70% ± 10.34% of the administered dose within 36 h post administration. <I>In vitro</I> serum protein binding was 41% ± 13.10%. Thus, a single daily intravenous dose of 4 mg/kg is sufficient to maintain effective levels in serum and for 36 h in urine, allowing treatment of systemic, Gram-negative bacterial infections and urinary tract infections by most pathogens.
