Posaconazole Enhances the Activity of Amphotericin B against Hyphae of Zygomycetes In Vitro

Abstract
The in vitro activity of posaconazole plus amphotericin B against conidia and hyphae of 30 clinical zygomycetes was investigated. The combination of posaconazole with amphotericin B was found to be significantly more synergistic (40%) against hyphae (P < 0.05) than against conidia (10%). Antagonism was not observed.
