Quantitative determination of telavancin in pregnant baboon plasma by solid-phase extraction and LC-ESI-MS.

ABSTRACT: The increasing incidence and severity of methicillin- and vancomycin-resistant infections during pregnancy prompted further development of telavancin. The understanding of the pharmacokinetics of telavancin during pregnancy is critical to optimize dosing. Due to ethical and safety concerns the study is conducted on the pregnant baboons. A method using solid-phase extraction coupled with liquid chromatography-single quadrupole mass spectrometry for the quantitative determination of telavancin in baboon plasma samples was developed and validated. Teicoplanin was used as an internal standard. Telavancin was extracted from baboon plasma samples by using Waters Oasis(®) MAX 96-Well SPE plate and achieved extraction recovery was >66% with variation <12%. Telavancin was separated on Waters Symmet
