Fluconazole belongs to a class of antifungal medications called triazoles. It works by inhibiting the synthesis of ergosterol, a critical component of fungal cell membranes. This disruption weakens the cell membrane, leading to cell death or inhibiting fungal growth [4].
What Conditions Does Diflucan (Fluconazole) Treat?
