Abstract:OBJECTIVE To study the pharmacokinetic profiles of oral busulfan in Chinese patients undergoing allogeneic hematopoietic stem cell transplantation. METHODS Blood samples of 9 adult patients were collected following the first and the ninth dose of standard 16 doses of oral busulfan,4-day regimen. The plasma concentrations of busulfan were determined by HPLC, and the pharmacokinetic parameters of busulfan were calculated by DAS statistical software. RESULTS The plasma concentration- time curves after dose 1 and dose 9 of oral 1 mg·kg-1 busulfan in 9 patients were described by an one-compartment model,respectively. The main pharmacokinetic parameters were as followst1/2 (133.0±30.6)and(131.4±28.2)min, Ke (0.005±0.001)and(0.006±0.001)min-1, Vd/F(0.56±0.12)and(0.46±0.08)L·kg-1, CL/F(0.003±0.001)and(0.002±0.001)L·min-1·kg-1, AUC0-t(910.3±146.9)and(1 158.5±139.0)μmol·min·L-1, AUC0-∞(1 401.9±243.2)and(1 689.0±312.4) μmol·min·L-1,respectively. Busulfan average steady state plasma concentration was (3.29±0.39)μmol·L-1. CONCLUSION The pharmacokinetic profiles of oral busulfan are fitted to an one-compartment model,and the main pharmacokinetic parameters are significant difference between dose 1 and dose 9.
