Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits fungal squalene epoxidase, thereby blocking ergosterol biosynthesis and causing accumulation of squalene, 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.
Butenafine hydrochloride 1% cream: apply to affected area once daily for 2 weeks for tinea pedis; for tinea corporis and tinea cruris, apply once daily for 1 week.
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 5-6 hours; clinical significance: supports twice-daily dosing for topical antifungal therapy.
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 (biliary) as unchanged drug and metabolites; renal excretion of metabolites accounts for less than 1% of the dose.
Primarily fecal (57%) via biliary excretion as unchanged drug and metabolites; renal excretion accounts for approximately 13% (2-4% unchanged).
