RT Journal Article T1 Pharmacokinetic behaviour of enrofloxacin in greater rheas following a single-dose intramuscular administration A1 Lucas Burneo, José Julio De A1 Navarro, J. L., A1 Rubio Langre, Sonia A1 Vignolo, P. E. A1 Asis, V. C. A1 González Gómez, Fernando A1 Rodríguez Fernández, Casilda AB The pharmacokinetic behaviour of enrofloxacin in greater rheas was investigated after intramuscular (IM) administration of 15 mg/kg. Plasma concentrations of enrofloxacin and its active metabolite, ciprofloxacin, were determined by high performance liquid chromatography. Enrofloxacin peak plasma concentration (Cmax = 3.30 ± 0.90 μg/mL) was reached at 24.17 ± 9.17 min. The terminal half-life (t1/2λ) and area under the curve (AUC) were 2.85 ± 0.54 h and 4.18 ± 0.69 μg h/mL, respectively. The AUC and Cmax for ciprofloxacin were 0.25 ± 0.06 μg/mL and 0.66 ± 0.16 μg h/mL, respectively. Taking into account the values obtained for the efficacy indices, an IM dose of 15 mg/kg of enrofloxacin would appear to be adequate for treating infections caused by highly susceptible bacteria (MIC90 < 0.03 μg/mL) in greater rheas.
