Abstract:
:We developed a high-performance liquid chromatography (HPLC) assay to validate time-kill and postantifungal-effect (PAFE) experiments for voriconazole against Candida albicans, Candida glabrata, and Candida parapsilosis isolates. Voriconazole exerted prolonged fungistatic activity but no PAFE at concentrations achievable in human sera. HPLC confirmed that experiments were conducted at the desired steady-state voriconazole concentrations.
