Description
Nystatin is an antimycotic polyene antibiotic obtained from Streptomyces noursei . Its structural formula:
C47H75NO17 M.W. 926.13
Nystatin tablets are for oral administration and contain 500,000 units of nystatin per tablet.
Nystatin tablets contain the inactive ingredients: corn starch, confectioner sugar, dibasic calcium phosphate, FD&C yellow #6, FD&C red #40, FD&C blue # 2, hydroxypropyl cellulose, hypromellose, microcrystalline cellulose, magnesium stearate, polyethylene glycol, polysorbate 80, talc and titanium dioxide.
Other
Tachycardia, bronchospasm, facial swelling, and nonspecific myalgia have also been rarely reported.
To report SUSPECTED ADVERSE REACTIONS, contact Avet Pharmaceuticals Inc. at 1-866-901-DRUG (3784) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
General
This medication is not to be used for the treatment of systemic mycoses. Discontinue treatment if sensitization or irritation is reported during use.
Overdosage
Oral doses of nystatin in excess of five million units daily have caused nausea and gastrointestinal upset. There have been no reports of serious toxic effects of superinfections (see CLINICAL PHARMACOLOGY, Pharmacokinetics ).
Dermatologic
Rash, including urticaria has been reported rarely. Stevens-Johnson syndrome has been reported very rarely.
Microbiology
Nystatin is both fungistatic and fungicidal in vitro against a wide variety of yeasts and yeast-like fungi. Candida albicans demonstrates no significant resistance to nystatin in vitro on repeated subculture in increasing levels of nystatin; other Candida species become quite resistant. Generally, resistance does not develop in vivo. Nystatin acts by binding to sterols in the cell membrane of susceptible Candida species with a resultant change in membrane permeability allowing leakage of intracellular components. Nystatin exhibits no appreciable activity against bacteria, protozoa, or viruses.
Nursing Mothers
It is not known whether nystatin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when nystatin is administered to a nursing woman.
Gastrointestinal
Diarrhea (including one case of bloody diarrhea), nausea, vomiting, gastrointestinal upset/disturbances.
Pharmacokinetics
Gastrointestinal absorption of nystatin is insignificant. Most orally administered nystatin is passed unchanged in the stool. In patients with renal insufficiency receiving oral therapy with conventional dosage forms, significant plasma concentrations of nystatin may occasionally occur.
Teratogenic Effects
Category C
Animal reproduction studies have not been conducted with nystatin. It is also not known whether nystatin can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Nystatin should be given to a pregnant woman only if clearly needed.
