Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Butenafine hydrochloride is a synthetic antifungal agent that inhibits the enzyme squalene epoxidase, thereby blocking the biosynthesis of ergosterol, an essential component of fungal cell membranes, leading to fungal cell death.
Ketoconazole, an imidazole antifungal agent, inhibits fungal cytochrome P450 14α-demethylase (CYP51), preventing the conversion of lanosterol to ergosterol, an essential component of fungal cell membranes. This disrupts membrane integrity and function.
Adults: Apply butenafine hydrochloride 1% cream topically once daily for 7 days for tinea pedis; for tinea cruris and tinea corporis, apply once daily for 14 days.
Apply to wet hair, lather, and leave on for 3-5 minutes before rinsing. Use twice weekly for 4 weeks, then as needed to control dandruff.

Terminal elimination half-life is approximately 24-48 hours (range 20-50 hours), supporting once-daily topical application.
Terminal elimination half-life is biphasic: initial 2 hours, terminal 8 hours (range 6-10 hours). After topical application, systemic absorption is minimal, resulting in an effective half-life of 72-96 hours in skin.
Primarily fecal (approx. 80%) as unchanged drug and metabolites; renal excretion accounts for <10% of the dose.
Primarily fecal (57%) via biliary excretion as unchanged drug and metabolites; renal excretion accounts for approximately 13% (2-4% unchanged).
