Nystatin is a mixture of the byproducts of Streptomyces noursei. Nystatin belongs to the group of medicines called antifungals. Nystatin works by binding to a substance called ergosterol, which is a component of fungal cell membranes. Binding to ergosterol disrupts the cell membrane and causes holes to appear.
