<p>Nystatin is an antifungal antibiotic. Which has fungistatic or fungicidal activity against variety of pathogenic and nonpathogenic yeast and fungi, including Candida albicans. Nystatin exerts its antifungal activity by binding to sterols in the fungal cell membrane. As a result of binding, the membrane is no longer able to function as a selective barrier, and potassium and other cellular constituents are lost. It is poorly absorbed from the gastrointestinal tract.</p>
