Özet
In this study, the pharmacokinetics of moxifloxacin (5 mg/kg) was determined following a single intravenous administration of moxifloxacin alone and co-administration with diclofenac (2.5 mg/kg) or flunixin meglumine (2.2 mg/kg) in sheep. Six healthy Akkaraman sheep (2 +/- 0.3 years and 53.5 +/- 5 kg of body weight) were used. A longitudinal design with a 15-day washout period was used in three periods. In the first period, moxifloxacin was administered by an intravenous (IV) injection. In the second and third periods, moxifloxacin was co-administered with IV administration of diclofenac and flunixin meglumine, respectively. The plasma concentration of moxifloxacin was assayed by high-performance liquid chromatography. The pharmacokinetic parameters were calculated using a two-compartment open pharmacokinetic model. Following IV administration of moxifloxacin alone, the mean elimination half-life (t(1/2 beta)), total body clearance (Cl-T), volume of distribution at steady state (V-dss) and area under the curve (AUC) of moxifloxacin were 2.27 hr, 0.56 L h(-1) kg(-1), 1.66 L/kg and 8.91 hr*mu g/ml, respectively. While diclofenac and flunixin meglumine significantly increased the t(1/2 beta) and AUC of moxifloxacin, they significantly reduced the Cl-T and V-dss. These results suggest that anti-inflammatory drugs could increase the therapeutic efficacy of moxifloxacin by altering its pharmacokinetics.
