Mechanism of action

Voriconazole is a triazole antifungal that selectively targets fungal sterol synthesis by inhibiting the enzyme lanosterol 14α-demethylase (CYP51). This prevents the conversion of lanosterol to ergosterol, a critical component of the fungal cell membrane. The resulting depletion of ergosterol and accumulation of toxic sterol precursors leads to fungal cell membrane instability and cell death. High-dose regimens are used to achieve adequate tissue penetration, particularly in the central nervous system and for treatment of invasive infections.
