|Background: Busulfan (Bu) is an alkylating agent commonly used in preparative regimens for patients undergoing hematopoietic stem cell transplantation (HSCT) for various types of malignancies. A rapid, selective, reliable, precise, accurate, and reproducible method for quantification of Bu in human plasma using Acquity UPLC system coupled to triple quadrupole tandem mass detector (TQD) has been developed and validated to be used routinely for TDM of Bu employing Busulfan-d8 as an internal standard (IS). Methods: The drug and IS were extracted by ether and analyzed on Acquity UPLC BEH C18 column (2.1x50 mm, 1.7 μm). Quantitation was achieved using positive electrospray ion source (ESI+) interface employing MRM mode. Results: The method was validated over the concentration range of 25–2000 ng/ml (r>0.99). Intra- and inter-run precision of Bu assay at four concentrations (50, 500, 1250 and 1750 ng/ml) ranged from 1.2 to 6.5% with accuracy (bias) varied from –10.7 to –0.2% indicating good precision and accuracy. Stability of Bu in human plasma samples at different conditions showed that the drug was stable under the studied conditions. Conclusion: The suitability of the developed method for routine TDM was demonstrated by measuring Bu in human plasma samples of patients under preparative and conditioning regimens who will undergo hematopoietic cell transplantation (HCT) for various malignancies including acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) as well as nonmalignancy conditions such as thalassemias.|
