Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole inhibits fungal lanosterol 14α-demethylase, a cytochrome P450 enzyme, thereby 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 once daily to affected areas for 2-4 weeks. Vaginal: One 200 mg suppository at bedtime for 3 days, or one 100 mg suppository at bedtime for 7 days, or one 1200 mg suppository as a single dose.
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 24–30 hours, supporting twice-daily or once-daily dosing for dermatologic 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.
Primarily fecal (biliary) elimination as unchanged drug and metabolites; <1% renal excretion of unchanged drug.
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.
