title: Distribution of voriconazole in seven body fluids of adult horses after repeated oral dosing.
abstract: The purpose of this study was to assess safety and alterations in body fluid concentrations of voriconazole in normal horses on days 7 and 14 following once daily dose of 4 mg/kg of voriconazole orally for 14 days. Body fluid drug concentrations were determined by the use of high performance liquid chromatography (HPLC). On day 7, mean voriconazole concentrations of plasma, peritoneal, synovial and cerebrospinal fluids, aqueous humor, epithelial lining fluid (ELF), and urine were 1.47 +/- 0.63, 0.61 +/- 0.22, 0.70 +/- 0.20, 0.62 +/- 0.26, 0.55 +/- 0.32, 79.45 +/- 69.4, and 1.83 +/- 0.44 microg/mL respectively. Mean voriconazole concentrations in the plasma, peritoneal, synovial and cerebrospinal fluids, aqueous humor, ELF and urine on day 14 were 1.60 +/- 0.37, 1.02 +/- 0.27, 0.86 +/- 0.25, 0.64 +/- 0.21, 0.68 +/- 0.13, 47.76 +/- 45.4 and 3.34 +/- 2.17 respectively. Voriconazole concentrations in the bronchoalveolar cell pellet were below the limit of detection. There was no statistically significant difference between voriconazole concentrations of body fluids when comparing days 7 and 14. Results indicated that voriconazole distributes widely into body fluids.
