Medicine Description vfend 200mg
Vfend 200mg Ampoules is a medication that functions primarily through the inhibition of fungal ergosterol synthesis. Specifically, it targets the cytochrome P450 enzyme, 14-alpha sterol demethylase. This enzyme is crucial for converting lanosterol to ergosterol, an essential component of the fungal cell membrane. By inhibiting this enzyme, voriconazole disrupts the normal synthesis of ergosterol, leading to an unstable and dysfunctional cell membrane. The resultant depletion of ergosterol impairs fungal cell growth and replication, ultimately resulting in the death of the pathogen. Voriconazole exhibits broad-spectrum antifungal activity, making it effective against various pathogenic fungi, including those resistant to other antifungal agents.
