Mechanism :

Nystatin is both fungistatic and fungicidal in vitro against a wide variety of yeasts and yeast-like fungi. Nystatin acts by binding to sterols in the cell membrane of susceptible fungi with a resultant change in membrane permeability allowing leakage of intracellular components. Nystatin exhibits no activity against bacteria, protozoa, trichomonads, or viruses.
