title: Liquid-chromatographic determination of fleroxacin in serum and urine.
abstract: This highly sensitive, accurate, and reproducible HPLC method for determining fleroxacin in human serum and urine makes use of a common C18 column, a fluorescence detector, and an internal standard. Serum samples require a simple extraction procedure; urine must be diluted. The method, which we have used extensively for pharmacokinetic assessment of fleroxacin in patients, measures concentrations as low as 5 micrograms/L.
