DESCRIPTION Nystatin is a polyene antifungal antibiotic drug obtained from Streptomyces nursei. Structural formula: Nystatin Ointment is for dermatologic use. Nystatin Ointment USP, for topical use only, contains 100,000 USP Nystatin Units per gram, in a white petrolatum and light mineral oil base.

DOSAGE AND ADMINISTRATION NYSTATIN Ointment Adults and Pediatric Patients (Neonates and Older): Apply liberally to affected areas twice daily or as indicated until healing is complete.

INDICATIONS AND USAGE Nystatin Ointment is indicated in the treatment of cutaneous or mucocutaneous mycotic infections caused by Candida albicans and other susceptible Candida species. Nystatin Ointment is not indicated for systemic, oral, intravaginal or ophthalmic use.

CLINICAL PHARMACOLOGY Pharmacokinetics Nystatin is not absorbed from intact skin or mucous membrane. Microbiology Nystatin is an antibiotic which is both fungistatic and fungicidal in vitro against a wide variety of yeasts and yeast-like fungi, including Candida albicans, C.parapsilosis, C.tropicalis, C.guilliermondi, C. pseudotropicalis, C. krusei, Torulopsis glabrata, Tricophyton rubrum, T. mentagrophytes . Nystatin acts by binding to sterols in the cell membrane of susceptible species resulting in a change in membrane permeability and the subsequent leakage of intracellular components. On repeated subculturing with increasing concentrations of nystatin, Candida albicans does not develop resistance to nystatin. Generally, resistance to nystatin does not develop during therapy. However, other species of Candida ( C. tropicalis, C. guilliermondi, C. krusei, and C. stellatoides ) become quite resistant on treatment with nystatin and simultaneously become cross resistant to amphotericin as well. This resistance is lost when the antibiotic is removed. Nystatin exhibits no appreciable activity against bacteria, protozoa, or viruses.

Pharmacokinetics Nystatin is not absorbed from intact skin or mucous membrane.
