Abstract:
Background: The simultaneous use of NSAIDs and antibiotics is recommended for bacterial diseases
in human and veterinary medicine. Moxifloxacin (MFX) and dexketoprofen (DEX) can be used simultaneously
in bacterial infections. However, there are no studies on how the simultaneous use of DEX affects
the pharmacokinetics of MFX in rats.
Objectives: The aim of this study was to determine the effect of DEX on plasma and lung pharmacokinetics
of MFX in male and female rats.
Methods: A total of 132 rats were randomly divided into 2 groups: MFX (n=66, 33 males/33 females) and
MFX+DEX (n=66, 33 females/33 males). MFX at a dose of 20 mg/kg and DEX at a dose of 25 mg/kg were
administered intraperitoneally. Plasma and lung concentrations of MFX were determined using the highperformance
liquid chromatography-UV and pharmacokinetic parameters were evaluated by noncompartmental
analysis.
Results: Simultaneous administration of DEX increased the plasma and lung area under the curve from 0 to
8 h (AUC0-8) and peak concentration (Cmax) of MFX in rats, while it significantly decreased the total body
clearance (CL/F). When female and male rats were compared, significant differences were detected in
AUC0-8, Cmax, CL/F and volume of distribution. The AUC0-8lung/AUC0-8plasma ratios of MFX were calculated as
1.68 and 1.65 in female rats and 5.15 and 4.90 in male rats after single and combined use, respectively.
Conclusion: MFX was highly transferred to the lung tissue and this passage was remarkably higher in male
rats. However, DEX administration increased the plasma concentration of MFX in both male and female rats
but did not change its passage to the lung. However, there is a need for a more detailed investigation of the
difference in the pharmacokinetics of MFX in male and female rats.
