Most fungi are resistant to conventional antimicrobial agents, and relatively few drugs are available for the treatment of systemic fungal diseases. Amphotericin B, the azoles (fluconazole, itraconazole, ketoconazole, and voriconazole), and the echinocandins are the primary drugs used in systemic infections. They are selectively toxic to fungi because they interact with or inhibit the synthesis of ergosterol, a sterol unique to fungal cell membranes.
