Nystatin Oral Suspension - 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 vitroagainst a wide variety of yeasts and yeast-like fungi. Candida albicansdemonstrates no significant resistance to nystatin in vitroon repeated subculture in increasing levels of nystatin; other Candidaspecies become quite resistant. Generally, resistance does not develop in vivo. Nystatin acts by binding to sterols in the cell membrane of susceptible Candidaspecies with a resultant change in membrane permeability allowing leakage of intracellular components. Nystatin exhibits no appreciable activity against bacteria, protozoa, or viruses.
Indications and Usage for Nystatin Oral Suspension
Nystatin Oral Suspension is indicated for the treatment of candidiasis in the oral cavity.
Contraindications
The preparation is contraindicated in patients with a history of hypersensitivity to any of its components.
Precautions

Carcinogenesis, Mutagenesis, Impairment of Fertility
No long-term animal studies have been performed to evaluate carcinogenic potential. There also have been no studies to determine mutagenicity or whether this medication affects fertility in males or females.
