Objectives: The in vitro antifungal activity of posaconazole was compared with that of fluconazole and amphotericin B.
Materials and methods: A microdilution method (M27-A2) was used with 331 clinical yeast isolates.
Results: The geometric mean MICs of posaconazole, fluconazole and amphotericin B were 0.16, 0.91 and 0.15 mg/L, respectively. Posaconazole was markedly more active than fluconazole and was active against 9/11 fluconazole-resistant Candida albicans, and five Candida glabrata had an MIC of posaconazole of 16 mg/L.
Conclusions: These data indicate that posaconazole is a potentially effective antifungal agent for the treatment of mycoses caused by yeasts.
