Distribution of marbofloxacin within the bronchoalveolar region of healthy pigs

The purpose of this study was to clarify the distribution of marbofloxacin (MBFX) within the bronchoalveolar region of pigs. Four clinically healthy pigs were intramuscularly injected with a single dose of MBFX (2 mg/kg). Samples of plasma and bronchoalveolar lavage fluid (BALF) were obtained for ea...

Description
Summary:The purpose of this study was to clarify the distribution of marbofloxacin (MBFX) within the bronchoalveolar region of pigs. Four clinically healthy pigs were intramuscularly injected with a single dose of MBFX (2 mg/kg). Samples of plasma and bronchoalveolar lavage fluid (BALF) were obtained for each pig at 0 (before administration), 3, 8 and 24 hr after administration of MBFX. As a result, the MBFX concentrations in pulmonary epithelial lining fluid (ELF) and in alveolar cells showed a similar pattern of concentrations during the experimental period. The MBFX concentrations both in ELF and alveolar cells were higher than in plasma. These results suggest that intramuscularly injected MBFX was well distributed in the bronchoalveolar region.
