Itraconazole belongs to a class of antifungal medications called triazoles. It works by inhibiting the synthesis of ergosterol, a critical component of fungal cell membranes. By disrupting ergosterol production, itraconazole weakens the fungal cell membrane, leading to increased permeability and cell death [1].
