Abstract: Busulfan (Bu; 1,4-butanediol dimethanesulphonate) prescribed as a chemotherapy drug prescribed in suppressing bone marrow in cancer. Determination of busulfan concentration in patients undergoing bone marrow transplantation is necessary in order to reduce toxic effects and/or graft rejection due to unadjusted dose exposure. A new extraction method namely dispersive micro solid-phase extraction (DMSPE) based on mesoporous sorbent was used for cleaning-up the plasma samples. The melamine-formaldehyde polymer as sorbent was synthesized using a simple, one-pot polycondensation reaction by using cost-effective and abundant materials and used in drug extraction. DMSPE coupling with liquid chromatography with tandem mass spectrometry (LC-MS/MS) was implemented for the determination of the busulfan dosage in plasma samples. The linear range was found from 10-2000 ng/ml. The precision and accuracy were found better than 15% according to Food and drug administration (FDA) guideline. This method was successfully used to determine the busulfan in patients administrated busulfan as part of the preparative regimen for bone marrow transplantation.
