Solid-phase membrane tip extraction combined with liquid chromatography for the determination of azole antifungal drugs in human plasma
A simple and efficient solid-phase membrane tip extraction (SPMTE) was developed using mesoporous silica MCM-41 adsorbent for the determination of three azole antifungal drugs in human plasma prior to high performance liquid chromatography (HPLC). Three azole drugs, namely voriconazole (VRZ), ketoco...
