Dosage And Administration

DOSAGE AND ADMINISTRATION The usual therapeutic dosage is one to two tablets (500,000 to 1,000,000 units nystatin) three times daily. Treatment should generally be continued for at least 48 hours after clinical cure to prevent relapse.

Indications And Usage

INDICATIONS AND USAGE Nystatin Tablets are intended for the treatment of non-esophageal mucus membrane gastrointestinal candidiasis.

Overdosage

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 ).

Clinical Pharmacology

CLINICAL PHARMACOLOGY 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. 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 s pecies with a resultant change in membrane permeability allowing leakage of intracellular components. Nystatin exhibits no appreciable activity against bacteria, protozoa, or viruses.
