Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits fungal CYP450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Posaconazole inhibits fungal CYP450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Topical: Apply twice daily for 2-4 weeks. Vaginal: 200 mg suppository at bedtime for 3 days, or 100 mg suppository at bedtime for 7 days, or 1200 mg suppository as a single dose. Oral (buccal): 50 mg once daily for 14 days.
300 mg (one 300-mg vial) intravenously twice on day 1, then 300 mg intravenously once daily starting on day 2. Alternatively, oral suspension: 200 mg (10 mL) three times daily. For prophylaxis, IV: 300 mg twice on day 1, then 300 mg once daily; oral: 200 mg three times daily.

Terminal elimination half-life is approximately 24 hours (range 20-40 hours) following intravenous administration. This extended half-life supports twice-daily dosing for systemic infections.
The terminal elimination half-life is approximately 27 hours (range 20-66 hours) in healthy subjects, allowing for once-daily dosing after steady state.
Miconazole is primarily metabolized in the liver, with less than 1% of an intravenous dose excreted unchanged in urine. Biliary/fecal elimination accounts for approximately 50% of the dose as metabolites. Renal elimination of metabolites is minimal.
Posaconazole is primarily excreted in the feces (77%) as unchanged drug, with renal excretion accounting for 14% of the dose (primarily as glucuronide conjugates). Less than 0.2% is excreted unchanged in urine.
