Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to microtubules and disrupts mitotic spindle formation, inhibiting fungal cell division.
Nystatin binds to sterols in the fungal cell membrane, primarily ergosterol, altering membrane permeability and causing leakage of intracellular components, leading to fungal cell death.
500 mg orally once daily or 250 mg orally twice daily for dermatophyte infections.
Oral: 500,000 to 1,000,000 units (5-10 mL suspension) swish and swallow 3-4 times daily; Vaginal: 1 vaginal tablet (100,000 units) once or twice daily; Topical: Apply cream/ointment 2-3 times daily; duration depends on indication.

Terminal elimination half-life: 9–24 hours (mean ~14 hours). Clinical context: Steady-state achieved in 3–5 days; once-daily dosing is effective due to prolonged half-life.
Clinical Note
moderateNystatin + Tranilast
"The risk or severity of adverse effects can be increased when Nystatin is combined with Tranilast."
Clinical Note
moderateNystatin + Tolfenamic acid
"The risk or severity of adverse effects can be increased when Nystatin is combined with Tolfenamic acid."
Clinical Note
moderateNystatin + Nimesulide
"The risk or severity of adverse effects can be increased when Nystatin is combined with Nimesulide."
Clinical Note
moderateNystatin + Risedronic acid
Due to minimal systemic absorption, a terminal elimination half-life is not clinically relevant. In vitro plasma degradation half-life is approximately 1.5 hours, but this is not applicable in vivo.
Renal: <1% as intact drug; fecal: >99% as metabolites (mainly 6-demethylgriseofulvin glucuronide) via bile; negligible biliary excretion of parent compound.
Nystatin is not absorbed from the gastrointestinal tract after oral administration; virtually 100% of the ingested dose is excreted unchanged in the feces. After topical application, systemic absorption is negligible; any absorbed drug is excreted via bile and feces (<1% renal).
