Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to ergosterol in fungal cell membranes, forming pores that increase permeability, leading to leakage of intracellular contents and cell death.
Inhibits fungal CYP450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
IV: 0.25-1 mg/kg/day as a single infusion; for aspergillosis, up to 1.5 mg/kg/day; maximum daily dose 1.5 mg/kg.
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.

Terminal elimination half-life is approximately 15 days (range 10-20 days) after a single dose; with prolonged therapy, a prolonged terminal half-life of up to 15 days reflects slow redistribution from tissue depots.
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.
Primarily fecal (40-50%) via biliary elimination without metabolism; renal excretion of unchanged drug is minimal (<5% in 24 hours).
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.
