These agents may change the permeability of the fungal cell, resulting in a fungicidal effect.

Nystatin (Bio-Statin)

Nystatin is used to prevent fungal infections in mucositis. This agent is a fungicidal and fungistatic antibiotic from Streptomyces noursei that is effective against various yeasts and yeastlike fungi. Nystatin acts by changing the permeability of the fungal cell membrane after binding to cell membrane sterols, causing cellular contents to leak.

Treatment with this agent should continue until 48 hours after the symptoms disappear. Nystatin is not substantially absorbed from the gastrointestinal tract.


Clotrimazole may be used instead of nystatin to prevent fungal infections. It is a broad-spectrum antifungal agent that inhibits yeast growth by altering cell membrane permeability, causing death of fungal cells.

Itraconazole (Onmel; Sporanox; Sporanox Pulsepak)

Itraconazole has fungistatic activity and is used to prevent fungal infections in high-risk patients. This drug is a synthetic triazole antifungal agent that slows fungal cell growth by inhibiting CYP-dependent synthesis of ergosterol, a vital component of fungal cell membranes. The bioavailability of this drug is greater in the oral solution compared with the capsule formulation.
