Pharmacology & Mechanism of Action
Voriconazole is a triazole antifungal medication used to treat serious fungal infections. Voriconazole binds and inhibits ergosterol synthesis by inhibiting CYP450-dependent 14-alpha sterol demethylase. The inhibition of 14-alpha sterol demethylase results in a depletion of ergosterol in fungal cell membrane.
