The in-vitro activity of the triazole antifungal agent voriconazole was
compared with itraconazole and amphotericin B against 60 aspergillus
isolates. Susceptibility tests were performed using two methods: a
macrodilution and a microdulution method. For macrodilution methodology,
geometric mean (GM) MIC values and ranges were 0.4 and 0.125-4 mg/L for
voriconazole, 0.24 and 0.06-->16 mg/L for itraconazole, and 1.04 and
0.5-4 mg/L for amphotericin B. For the microdilution method, GM MICs and
ranges were 0.66 and 0.125-2 mg/L for voriconazole, 0.27 and 0.06-->16
mg/L for itraconazole, and 1.62 and 0.25-32 mg/L for amphotericin B. In
conclusion, voriconazole is active against Aspergillus spp. in vitro, and
at similar concentrations to itraconazole.
