Development and validation of a liquid chromatographic-tandem mass spectrometric method for the multiplexed quantification of etravirine, maraviroc, raltegravir, and rilpivirine in human plasma and tissue

摘要

Background: Analytical methodologies for antiretroviral (ARV) quantification are important in determining both systemic and localized drug concentrations. The CCR5-antagonist maraviroc (MVC), the non-nucleoside reverse transcriptase inhibitors (NNRTIs) etravirine (ETV) and rilpivirine (RPV), as well as the integrase strand transfer inhibitor (INSTI) raltegravir (RAL), have all been evaluated using both oral and non-oral dosing regimens, demonstrating a need for dynamic and sensitive bioanalytical tools for drug quantification in plasma and tissue.
