Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole inhibits fungal cytochrome P450 14α-demethylase (CYP51), thereby blocking the conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane. This leads to increased membrane permeability and fungal cell death.
Inhibits fungal cytochrome P450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Intravaginal: 1 applicatorful (100 mg) at bedtime for 3 consecutive nights.
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 is 20-25 hours (intravaginal administration). This long half-life supports a 3-day dosing regimen, maintaining therapeutic concentrations.
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: approximately 10-20% as unchanged drug; fecal: >50% as metabolites; biliary: minor route. The majority is eliminated via feces as metabolites, reflecting hepatic metabolism and biliary excretion.
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).
