Bioanalysis of Darunavir in human plasma using Liquid Chromatography coupled with tandem mass spectrometry

2017 International Journal of PharmTech Research  
This paper describes a simple and rapid LC-MS/MS method for the determination of Darunavir in human plasma using carbamazepine as internal standard (IS). Analyte and the IS was extracted from the 100 µL of human plasma via protein precipitation (PP). The chromatographic separation was achieved on a C 18 column by using a mixture of 0.1% formic acid in acetonitrile -5mM ammonium acetate buffer (75:25, v/v) as the mobile phase at a flow rate of 0.7 mL/min. Detection involved an API-4000 LC-MS/MS

Method validation was performed as per FDA guidelines and the results met the acceptance criteria. The proposed method can adopt for the regular bioequivalence study analysis and also can easily adoptable for clinical drug monitoring due to its simplicity and ruggedness.

As per the literature, many LC-MS/MS methods have been reported for the simultaneous determination of darunavir along with the other anti-retroviral drugs 3,13 . But, those are having the limitation like 1) very complex and laborious extraction procedure, 2) longer run time, 3) lack of dynamic linearity range. But, the major concern in the world is treatment/control the progress of AIDS which demands the rapid turnover time in
