title: Fenofibrate and fenofibric acid analysis by capillary electrophoresis.
abstract: A capillary electrophoresis method has been developed to measure fenofibrate in capsules based on micellar electrokinetic capillary chromatography with detection at 280 nm using a borate buffer containing sodium dodecyl sulfate (SDS). However, the metabolite of this drug (fenofibric acid) in serum and whole blood was analyzed by capillary zone electrophoresis (CZE) in a borate-carbonate buffer using acetonitrile stacking. The analysis is rapid, < 7 min with no interferences. Incubation of fenofibrate in whole blood caused hydrolysis of the ester bond with the release of fenofibric acid.
