A spectrofluorometric assay was developed for the determination of the antibiotic lasalocid in dog blood, based on the intrinsic fluorescence of the compound in ethyl acetate. The assay can measure “total” levels of drug and any metabolites present. The specificity of the assay was verified by TLC separation of the dog blood extract, which indicated the presence of only intact drug. The overall recovery (±SD) of lasalocid was 62.0 ± 3.6% in the concentration range of 1.0–10 μg of compound/ml of dog blood. The sensitivity of the assay is 0.5 μg/ml. The assay was applied to the determination of blood levels of lasalocid in the dog following the intravenous administration of a 5-mg/kg dose. |
