CLINICAL PHARMACOLOGY

Pharmacokinetics

Gastrointestinal absorption of Naxogin Dos is insignificant. Most orally administered Naxogin Dos (Nystatin) is passed unchanged in the stool. In patients with renal insufficiency receiving oral therapy with conventional dosage forms, significant plasma concentrations of Naxogin Dos (Nystatin) may occasionally occur.

Microbiology

Naxogin Dos (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 Naxogin Dos (Nystatin) in vitro on repeated subculture in increasing levels of Naxogin Dos (Nystatin); other Candida species become quite resistant. Generally, resistance does not develop in vivo. Naxogin Dos (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. Naxogin Dos (Nystatin) exhibits no appreciable activity against bacteria, protozoa, or viruses.

INDICATIONS AND USAGE

Naxogin Dos (Nystatin) tablets are intended for the treatment of non-esophageal mucus membrane gastrointestinal candidiasis.

CONTRAINDICATIONS

Naxogin Dos (Nystatin) tablets are contraindicated in patients with a history of hypersensitivity to any of their components.
