Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Flucytosine is converted intracellularly to 5-fluorouracil, which inhibits fungal RNA and DNA synthesis by incorporating into RNA and inhibiting thymidylate synthase.
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.
50-150 mg/kg/day orally divided every 6 hours; intravenous dosing: 50-150 mg/kg/day divided every 12 hours.
8 mg/kg (max 800 mg) IV over 2 hours once daily for 14 days

Terminal elimination half-life 2.5-6 hours (normal renal function). Prolonged to 30-250 hours in renal impairment (CrCl < 20 mL/min). Half-life correlates with creatinine clearance.
Terminal elimination half-life is approximately 24 hours, supporting once-daily topical application.
Primarily renal excretion of unchanged drug (75-90% within 24 hours). Less than 1% eliminated as 5-fluorouracil metabolite. Biliary/fecal excretion negligible.
Primarily hepatic metabolism; renal excretion of metabolites accounts for approximately 88% of the dose, with negligible fecal excretion (<1% as unchanged drug).
