Abstract
A highly selective and sensitive liquid chromatography-tandem mass spectrometry method was developed and validated for the simultaneous determination of trantinterol and one of its major metabolites, 1-carbonyl trantinterol, in human plasma. An Oasis MCX 96-well solid-phase extraction cartridge and a SeQuantTM ZIC(®)-HILIC LC column were used for sample preparation and chromatographic separation, respectively. The analytes were monitored by a QTrap 5500 mass spectrometer with positive electrospray ionization. Multiple reaction monitoring was used for quantification using the precursor to product ion pairs of m/z 311.1 → 237.9 (trantinterol), m/z 325.1 → 251.9 (1-carbonyl trantinterol) and m/z 368.4 → 294.0 (bambuterol as internal standard). The assay had a calibration range from 0.2 to 50 pg/mL and a lower limit of quantification of 0.2 pg/mL for both trantinterol and 1-carbonyl trantinterol. The inter-day and intra-day precisions were <12.0% and the accuracies were within the range of 87.1-111%. The mean recovery ranged from 82.0 to 97.7% and internal standard normalized matrix effect from 0.813 to 0.899. The analytes were stable under all tested conditions. This validated method was successfully applied to a pilot pharmacokinetic study in healthy subjects administered a single 50 μg oral dose.
