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 cytochrome P450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Intravaginal administration: 100 mg (one applicatorful of 2% cream) once daily for 3 days; or 100 mg (one suppository) once daily for 3 days; or 5 g (one applicatorful of 4% cream) as a single dose.
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 half-life is approximately 21–24 hours, supporting once-daily or twice-weekly dosing for vaginal candidiasis.
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.
Primarily hepatic metabolism with <5% excreted unchanged in urine; fecal elimination accounts for ~30% of metabolites.
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).
