To explore the exposure-efficiency relationships of Bu-Cy regimen and evaluate the necessity of relative therapeutic drug monitoring (TDM), we developed a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to simultaneously quantify the busulfan and cyclophosphamide in human plasma.</p><p><strong>Methods: </strong>A simple LC-MS/MS bioassay for simultaneous determination of busulfan and cyclophosphamide using isotope dilution internal standardization has been established. Plasma samples were subjected to protein precipitation prior to their injection into a column for subsequent separation (Thermo Accucore aQ C<sub>18</sub>, 50 × 2.1 mm, 2.6 μm).
