Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Inhibits fungal squalene epoxidase, thereby blocking ergosterol biosynthesis and causing accumulation of squalene, leading to fungal cell death.
Topical: Apply twice daily (morning and evening) to affected area for 2-4 weeks. Intravaginal: One 200 mg suppository vaginally at bedtime for 3 days, or one 500 mg vaginal tablet as a single dose.
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.

Terminal elimination half-life of absorbed clotrimazole is approximately 3.5–4 hours, but this is clinically irrelevant due to negligible systemic absorption after topical application.
Terminal elimination half-life is approximately 5-6 hours; clinical significance: supports twice-daily dosing for topical antifungal therapy.
Less than 1% of topical clotrimazole is absorbed; absorbed drug is metabolized in the liver to inactive metabolites and excreted primarily in feces (approximately 69%) and urine (approximately 21%) via biliary and renal routes.
Primarily fecal (biliary) as unchanged drug and metabolites; renal excretion of metabolites accounts for less than 1% of the dose.
