Abstract

A new, sensitive and fast method for the simultaneous determination of pyrazinamide, isoniazid, streptomycin, ethambutol, and rifampicin in human plasma was developed and validated. The method required only 100 μL of plasma and one step for sample preparation by protein precipitation. The drugs were separated by using a hydrophilic interaction liquid chromatography (HILIC) column. The mobile phase was methanol and water (0.1 % formic acid and 5 mM ammonium acetate, pH 3.0 ± 0.1) in a ratio of 65:35 (v/v), which was eluted at an isocratic flow rate of 0.5 mL/min. Tandem mass spectrometry was performed with a triple-quadrupole tandem mass spectrometer. By use of the HILIC column, the detection was free of ion-pair reagents in the mobile phase, with no significant matrix effects. The total run time was less than 2 min for each sample. The method was validated by evaluating its selectivity, sensitivity, linearity, accuracy, and precision according to US Food and Drug Administration guidelines. The lower limit of quantification was 4.0 ng/mL for pyrazinamide, isoniazid, and rifampicin, 0.5 ng/mL for ethambutol, and 10.0 ng/mL for streptomycin. The intraday precision and interday precision were less than 9 %, with the accuracy ranging between −9.3 and 7.3 %. The method was successfully applied to therapeutic drug monitoring of 33 patients with tuberculosis after administration of standard antituberculosis drugs. The method has been proved to meet the high-throughput requirements in therapeutic drug monitoring.
