Plain-English summary
Eight healthy beagle dogs were given either 5 or 10 mg of fluconazole, an antifungal medication, to see how well it worked in their bodies. The study found that fluconazole levels in the dogs' blood increased with higher doses and multiple administrations. The dogs tolerated the medication well, and it was safe for short-term use. This information can help veterinarians determine the best dosing for treating fungal infections in dogs.

Abstract
BACKGROUND: Fluconazole can be effective in the treatment of superficial mycoses in dogs. However, the pharmacokinetics of fluconazole have not yet been evaluated to determine its optimal dosing regimen. OBJECTIVES: This study aimed to determine the plasma concentration of fluconazole after single and multiple administrations at two different dosages in dogs. METHODS AND MATERIALS: Eight healthy beagle dogs were divided into two groups, and each group received either 5 or 10 mg/kg of fluconazole per os. The pharmacokinetics of fluconazole was determined following single and multiple administrations p.o. Single- and multiple-dose treatment periods were separated by a washout period of seven days. Plasma concentrations of fluconazole were determined by established high-performance liquid chromatography coupled with tandem mass spectrometry system. RESULTS: In the 5 mg/kg group, the mean maximum concentrations (C) and the area under the plasma concentrations (AUC) were 4.84 μg/mL and 85.56 μg*h/mL, respectively, after single administration and 6.58 μg/mL and 119.52 μg*h/mL, respectively, after multiple administrations. In the 10 mg/kg group, the Cand AUCwere 5.67 μg/mL and 109.19 μg*h/mL, respectively, after single administration and 15.10 μg/mL and 291.51 μg*h/mL, respectively, after multiple administrations. The C(p < 0.001) and AUC(p < 0.001) were significantly lower in the 5 mg/kg group than those in the 10 mg/kg group at multiple administrations. CONCLUSIONS AND CLINICAL RELEVANCE: Fluconazole accumulates in plasma and exhibits dose-proportional pharmacokinetics after multiple doses, and was safe and well tolerated at these doses for short-term administration.
