Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits squalene epoxidase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Inhibits fungal cytochrome P450 14α-demethylase (CYP51), blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
1% cream applied topically once daily for 2 weeks for tinea pedis, 1 week for tinea corporis/cruris.
IV: Loading dose of 6 mg/kg every 12 hours for 2 doses, then 4 mg/kg every 12 hours. Oral: Weight ≥40 kg: Loading dose of 400 mg every 12 hours for 2 doses, then 200 mg every 12 hours; weight <40 kg: Loading dose of 200 mg every 12 hours for 2 doses, then 100 mg every 12 hours.

Terminal elimination half-life is approximately 35–40 hours following topical application; long half-life supports once-daily dosing.
Terminal half-life is approximately 24 hours (range 12–30 h) in adults. Prolonged in hepatic impairment (Child-Pugh A: 48 h; B: 72 h).
Primarily metabolized in the liver; minimal excretion of unchanged drug. Less than 5% of a topical dose is absorbed systemically; excreted in urine and feces as metabolites.
Primarily hepatic metabolism; <2% excreted unchanged in urine. Fecal excretion accounts for ~80% of metabolites. Renal excretion of unchanged drug is negligible.
