Validated assay for the determination of celiprolol in plasma using high-performance liquid chromatography and a silanol deactivated reversed-phase support Academic Article uri icon

abstract

  • Previously reported methods for the determination of celiprolol in plasma could not be satisfactorily employed due to interference from plasma components. Thus, an improved, convenient and efficient method for the determination of the plasma concentration of celiprolol was developed using a simple solvent extraction step followed by high-performance liquid chromatography on a silanol deactivated C18 column with fluorescence detection. The plasma interference was resolved from celiprolol and the typical trailing of basic compounds on reversed-phase HPLC was eliminated. The peak-area ratio versus plasma concentration was linear over the range of 5-1000 ng/ml and the detection limit was 5 ng/ml.
