Mechanism of action

Voriconazole is a triazole antifungal that selectively inhibits the cytochrome P450-dependent enzyme lanosterol 14α-demethylase (CYP51), which is essential for ergosterol biosynthesis in fungi. By blocking ergosterol production, the drug causes disruption of the fungal cell membrane integrity, leading to cell death. The low-dose formulation maintains antifungal efficacy while potentially reducing systemic exposure and associated adverse effects.
