Objective To establish a HPLC method to determine the concentration of voriconazole in human plasma for its clinical ap-plication in the curative drug concentration monitoring. Methods The serum sample was performed the precipitation treatment by acte-tonitrile, then HPLC - UV was adopted for detection. With nitrazepan as the internal standard, the chromatographic column was the Hy-persil ODS columm (200. 0 mm × 4. 6 mm, 5 μm), the mobile phase was 25 mmol / L potassium dihydrogen phosphate buffer solution -acetonitrile ( 32 : 68 ) . The detection wavelength was at 256 nm with a flow rate of 1 mL / min and the column temperature of 35 ℃ . Results The concentration of voriconazole in the range of 0. 3 - 12 μg / mL( r = 0. 999 3) showed the good linearity. The recovery rates of low, middle and high concentrations were (105. 0 ± 3. 6)% , (101. 9 ± 3. 3)% and (101. 1 ± 3. 4)% , respectively. The intra - day and inter - day RSD were both less than 5% . The limit of quantitation was 0. 3 μg / mL. Conclusion The established method is fast, accu-rate and suitable for the determination of blood voriconazole concentration.
