Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits fungal cytochrome P450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Econazole nitrate, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, disrupting ergosterol synthesis and increasing cell membrane permeability.
Posaconazole oral suspension: 200 mg (5 mL) three times daily with food. Oral delayed-release tablets: 300 mg twice daily on day 1, then 300 mg once daily thereafter with food. IV: 300 mg twice daily on day 1, then 300 mg once daily.
Apply a thin layer to affected area once daily for 4-4 weeks; duration depends on indication.

Terminal elimination half-life is approximately 25-30 hours (range 20-66 hours) in healthy subjects; in patients with hepatic impairment or critical illness, half-life may be prolonged up to 40-50 hours; supports once-daily dosing in most patients.
Terminal elimination half-life is approximately 24-30 hours in patients with normal renal function, allowing once-daily dosing.
Primarily hepatic metabolism (glucuronidation) with extensive enterohepatic recirculation; renal excretion accounts for <1% as unchanged drug; approximately 71% of a radiolabeled dose is eliminated in feces (as parent drug and metabolites) and 13% in urine (as metabolites).
Primarily renal: approximately 70% of an oral dose is excreted unchanged in urine; biliary/fecal excretion accounts for ~20%, with the remainder as metabolites.
