摘要: A quantitative liquid chromatography (LC)-mass spectrometry (MS)/MS method in human plasma was developed and validated for the tyrosine kinase inhibitors erlotinib, gefitinib, imatinib plasma. Pre-treatment of samples achieved by using liquid-liquid extraction D-8 as internal standard. Separation performed on a Waters Alliance 2795 LC system an XBridge RP18 column. The mass spectrometer Micromass equipped with electro spray ionization probe, operating positive mode. calibration curves were linear over concentration range 5 to 3,000; 3,000, 5,000 ng/mL, respectively. intraday interday accuracy ranged from 90% 110% precision within 5%. reported provided necessary linearity, precision, determine clinical research therapeutic drug monitoring.
