Simultaneous determination of ivabradine and its metabolites in human plasma by liquid chromatography--tandem mass spectrometry.

A rapid, selective, sensitive and reproducible liquid chromatographic method with tandem mass spectrometric detection has been developed and validated for the analysis of a new specific bradycardic agent, ivabradine (S 16257) and six potentially active metabolites in human plasma. Isolation of these compounds and of the internal standard was performed by an automated solid-phase extraction system using Oasis cartridges. Separation and detection of ivabradine and its metabolites were achieved using a C18 column and a MS-MS detector with a positive electrospray ionization source. Ivabradine and its metabolites gave a linear response ranging from 0.1 or 0.2 to 20 ng/ml and the limits of quantitation ranged from 0.1 to 0.2 ng/ml using a 0.5 ml plasma sample size. A complete validation demonstrated the method to be accurate, precise and specific for the simultaneous quantification of ivabradine and its metabolites in human plasma. The method was subsequently applied to the quantitative determination of ivabradine and its metabolites in human plasma samples from healthy volunteers participating in a clinical study to provide pharmacokinetic data.[1]
