چکیده انگلیسی
A rapid, selective and sensitive high-performance liquid chromatography tandem mass spectrometry (LC-MS/MS) method coupled with high flow direct-injection on-line extraction has been developed and validated for the simultaneous quantitation of nefazodone and its three active metabolites, hydroxynefazodone, triazole-dione (BMS-180492) and m-chlorophyenylpiperazine (mCPP) in human plasma. The method utilized d7-nefazodone, d7-hydroxynefazodone, d4-BMS-180492 and d4-mCPP as internal standards (IS). The plasma samples were injected into the LC-MS/MS system after simply adding the internal standard solution and centrifuging. The required extraction and chromatographic separation of the analytes were achieved on an Oasis® HLB column (on-line extraction column, 1 mm Ã 50 mm, 30 μm) and a conventional Luna C8 column (analytical column, 4.6 mm Ã 50 mm, 5 μm). Detection was by positive ion electrospray tandem mass spectrometry. The total analysis run time for each sample was 2 min, which included the time needed for on-line extraction, chromatographic separation and LC-MS/MS analysis. The assay was validated for each analyte and the concentrations ranged from 2.0 to 500 ng/ml for nefazodone, hydroxynefazodone and mCPP and from 4.0 to 1000 ng/ml for BMS-180492, respectively. The assay was used for the high-throughput sample analysis of thousands of pharmacokinetic study samples and was proven to be rapid, accurate, precise, sensitive, specific and rugged.
