Abstract

 

A sensitive and selective liquid chromatographic-tandem mass spectrometric (LC-MS-MS) method was developed to determine zidovudine (ZDV) in human urine. After solid-phase extraction with SPE cartridge, the urine sample was analyzed on a C18 column (Symmetry 3.5 µm; 75×4.6 mm i.d) interfaced with a triple quadrupole tandem mass spectrometer. Positive electrospray ionization was employed as the ionization source. The mobile phase consisted of water-acetonitrile (20:80, v/v).The method was linear over a concentration range of 10–1000 ng mL-1. The lower limit of quantitation was 10 ng mL-1. The intra-day and inter-day relative standard deviation across three validation runs over the entire concentration range was <9.5%. The accuracy determined at three concentrations (150, 350 and 750 ng mL-1 ZDV) was within ±0.73% in terms of relative errors.
