Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to tubulin, disrupting microtubule function and inhibiting fungal cell mitosis; deposited in keratin precursor cells, making keratin resistant to fungal invasion.
Econazole nitrate, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, disrupting ergosterol synthesis and increasing cell membrane permeability.
250-375 mg orally once daily or 500-750 mg orally once daily for severe infections.
Apply a thin layer to affected area once daily for 4-4 weeks; duration depends on indication.

9-24 hours (mean 15 hours); prolonged in liver disease.
Terminal elimination half-life is approximately 24-30 hours in patients with normal renal function, allowing once-daily dosing.
Renal (<1% unchanged); fecal (36% as metabolites); tissue deposition may persist for weeks.
Primarily renal: approximately 70% of an oral dose is excreted unchanged in urine; biliary/fecal excretion accounts for ~20%, with the remainder as metabolites.
