ABSTRACT
A new high-performance liquid chromatographic (HPLC) assay without any extraction procedure was developed for the quantification of fluindione in plasma using a 100-microl sample volume and coumarin as the internal standard. A deproteinization procedure was coupled with a reversed-phase HPLC separation using a 250x4.6 mm I.D. C18 column and a UV detector set at 280 nm. Peak height ratios were linear over the range 0.05 to 10 microg/ml (correlation coefficient >0.998). The method was found to be highly reproducible, as indicated by the low value obtained for the coefficient of variation C.V. < or = 6.1% (n = 10). The limit of quantification, estimated under the described conditions at a signal-to-noise ratio of three and with a C.V. lower than 20% for precision and accuracy, was 0.025 microg/ml. The total turnaround time was 25 min. After storage of blood samples at concentrations of 0.1, 0.5 and 2.5 microg/ml at room temperature and exposition to light for 120 h, no degradation of fluindione occurred. This micromethod is simple (no extraction step), fast and currently is being used for drug monitoring.
