Nystatin

Chemical Information
Nystatin is a polyene antifungal drug that has broad-spectrum fungicidal and fungistatic activity against a number of yeasts and fungi, most notably Candida species. It is one of the most effective antifungal agents synthesized by bacteria, in this case a strain of Streptomyces noursei, and is closely related to [amphotericin B], differing only slightly in structure. Nystatin has a greater antifungal activity than amphotericin B - parenterally administered nystatin, however, is associated with significant toxicity and is not available in a formulation appropriate for systemic use. As it undergoes very little absorption following oral or topical administration, nystatin's efficacy is limited to the treatment/prevention of cutaneous, mucocutaneous, and gastrointestinal fungal infections.
