DESCRIPTION
Each gram of Nystatin Ointment USP contains 100,000 units of nystatin in a white petrolatum base.
CLINICAL PHARMACOLOGY
Nystatin is an antifungal antibiotic which is both fungistatic and fungicidal in vitro, against a wide variety of yeasts and yeast-like fungi. It probably acts by binding to sterols in the cell membrane of the fungus with a resultant change in membrane permeability allowing leakage of intracellular components. Nystatin is a polyene antibiotic of undetermined structural formula that is obtained from Streptomyces noursei, and is the first well tolerated antifungal antibiotic of dependable efficacy for the treatment of cutaneous, oral and intestinal infections caused by Candida (Monilia) albicans and other Candida species. It exhibits no appreciable activity against bacteria.
Nystatin provides specific therapy for all localized forms of candidiasis. Symptomatic relief is rapid, often occurring within 24 to 72 hours after the initiation of treatment. Cure is effected both clinically and mycologically in most cases of localized candidiasis.
