Abstract
A sensitive, rapid and simple liquid chromatography芒�?�?electrospray ionization mass spectrometry (LC-ESI-MS/MS) method was developed for the quantitative determination of vilazodone in human plasma and to study the pharmacokinetic behavior of vilazodone in healthy Egyptian volunteers. With escitalopram as internal standard (IS), liquid/liquid extraction was used for the purification and pre-concentration of analytes from human plasma matrix using diethyl ether. The separation was performed on Acquity UPLC BEH shield RP C18 column (1.7 um, 2.1x150 mm). Isocratic elution was applied using methanol: 0.2% formic acid (90:10, v/v). Detection was performed on a triple-quadrupole tandem mass spectrometer with multiple reactions monitoring (MRM) mode via electrospray ionization (ESI) source at m/z 442.21 芒�?�? 155.23 for vilazodone and m/z 325.14 芒�?�? 109.2 for escitalopram. Linear calibration curves were obtained over the range of 1-200 ng/mL with the lower limit of quantification at 1 ng/mL. The intra- and inter-day precision showed relative standard deviation 芒�?陇 3.28%. The total run time was 1.5 min. This method was successfully applied for clinical pharmacokinetic investigation and preliminary metabolic study was carried out.Biography
