Nystatin is an antifungal antibiotic which is both fungistatic and fungicidal in vitro against a variety of yeasts and yeast-like fungi. It is a polyene antibiotic undetermined structural formula that is obtained from Streptomyces noursei.
Pharmacology: Nystatin acts by binding to sterols in the cell membrane of the fungus which interferes in the membrane permeability. It exhibits no appreciable activity against bacteria or trichomonads.
Following oral administration, nystatin is poorly absorbed with no detectable blood levels when given in the recommended doses. Most of the orally administered nystatin is passed unchanged in the stool.
