KERYDIN vs NYSTATIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
KERYDIN (tavaborole) is a boron-based antifungal that inhibits fungal protein synthesis by blocking the activity of leucyl-tRNA synthetase, thereby preventing aminoacylation of tRNA(Leu) and impairing protein synthesis in dermatophytes.
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.
8 mg/kg (max 800 mg) IV over 2 hours once daily for 14 days
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 is approximately 24 hours, supporting once-daily topical application.
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.
Primarily hepatic metabolism; renal excretion of metabolites accounts for approximately 88% of the dose, with negligible fecal excretion (<1% as unchanged drug).
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).
