In vitro activity of fluvastatin, a cholesterol-lowering agent, and synergy with flucanazole and itraconazole against Candida species and Cryptococcus neoformans

Abstract

Fluvastatin, a cholesterol-lowering drug, exhibited minimal activity (MICs of 64 to >128 microg/ml) against Candida species and Cryptococcus neoformans. When fluvastatin was combined with fluconazole or itraconazole, both synergistic and additive effects were noted (fractional inhibitory concentration indices of < or = 0.156 to 0.625; fractional lethal concentration indices of < or = 0.156 to 0.75). This combined fungicidal activity was confirmed by time-versus-killing studies.
