Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to microtubule-associated proteins, disrupting mitotic spindle formation and inhibiting fungal cell division.
Inhibits fungal cytochrome P450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
250 mg orally twice daily for tinea infections; 500 mg orally twice daily for onychomycosis. Administer with a fatty meal to enhance absorption.
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.

Terminal elimination half-life: 9–24 hours (mean ~16 hours). Clinical context: prolonged half-life allows once-daily dosing; steady-state achieved within 2–3 days.
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.
Renal (largely unchanged, <1% as metabolites); biliary/fecal (minor). Approximately 36% of a dose is excreted in urine within 6 hours, and up to 50% within 72 hours.
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).
