    Abstract

    Background: Bivalirudin is a direct thrombin inhibitor for patients with unstable angina undergoing
    percutaneous coronary intervention.
    Methods: A sensitive liquid chromatography-tandem mass spectrometry (LC/MS/MS) method was
    developed and validated for the determination of bivalirudin, in human plasma using nafarelin as internal
    standard (IS). Chromatographic separation was performed using a Shiseido MG3 mm column (2.0 × 50
    mm) with a gradient mobile phase consisting of water and acetonitrile containing 0.1 % formic acid at
    a flow rate of 0.4 mL/min, and total run time was within 5 min. Detection and quantification was
    performed by the mass spectrometer using a multiple reaction-monitoring mode at m/z 1091.0 → 650.3
    for bivalirudin, and m/z 662.1 → 249.3 for IS.
    Results: The assay was linear over a concentration range of 10 - 10000 ng/mL with a lower limit of
    quantification of 10 ng/mL in human plasma.
    Conclusion: This method was successfully applied for pharmacokinetics study after intravenous
    administration of bivalirudin to healthy Korean male volunteers.
