Abstract
An analytic assay based on automated sample preparation and liquid chromatography (LC) coupled with electrospray mass spectrometry (ESI-MS) was developed for the quantification of 6 protease inhibitors (PIs) and 3 nonnucleoside reverse transcriptase inhibitors (NNRTIs). The 6 PIs, amprenavir, indinavir, ritonavir, lopinavir, nelfinavir, and saquinavir, as well as the three NNRTIs, nevirapine, efavirenz, and delavirdine, require a succinct analysis technique for therapeutic drug monitoring in HIV/AIDS patients. After protein precipitation, samples were loaded on a C8, 10 x 4-mm extraction column, washed, and, after activation of the column-switching valve, backflushed onto the 30 x 2.1 mm C8 analytic column. [M+H] ions were detected in the selected ion mode. A nonlinear fit (y(-1) = a + b/x, all r2 > 0.999) for amprenavir, indinavir, ritonavir, lopinavir, nelfinavir, and saquinavir and a linear fit (y = ax + b, all r2 > 0.999) for nevirapine, efavirenz, and delavirdine led to best regression. Absolute recoveries were as follows: PIs > 81%; NNRTIs > 76%. Interday and intraday precision were <12.5% for the PIs and <11.7% for the NNRTIs. Interday and intraday accuracy were <12.2% for the PIs and <14.9% for the NNRTIs. Limits of qua...Continue Reading
