Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to microtubule-associated proteins and disrupts fungal mitotic spindle formation, thereby inhibiting fungal cell division. It also interferes with fungal nucleic acid synthesis.
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.
500 mg orally once daily (non-microsize formulation) or 250 mg twice daily; typical duration is 4-8 weeks for tinea capitis, 2-6 weeks for tinea corporis, 4-6 weeks for tinea pedis.
8 mg/kg (max 800 mg) IV over 2 hours once daily for 14 days

Terminal half-life: 9–24 hours. Clinical context: Steady-state achieved in 2–5 days; prolonged in hepatic impairment.
Terminal elimination half-life is approximately 24 hours, supporting once-daily topical application.
Renal (1% unchanged), fecal (33% as metabolites), biliary (minor). Extensive hepatic metabolism; <1% excreted unchanged in urine.
Primarily hepatic metabolism; renal excretion of metabolites accounts for approximately 88% of the dose, with negligible fecal excretion (<1% as unchanged drug).
