Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amphotericin B binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity, leading to leakage of intracellular contents and cell death.
Miconazole inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Initial dose: 0.5 mg/kg intravenously once daily, titrated as tolerated to 5 mg/kg once daily.
Insert one miconazole nitrate 200 mg vaginal suppository intravaginally once daily at bedtime for 3 consecutive days. Apply intravaginal cream as needed for symptom relief.

Terminal half-life: 24-48 hours (up to 7 days in hepatic impairment). Long half-life allows once-daily dosing.
After intravenous administration, the terminal elimination half-life is approximately 20-24 hours; after topical or intravaginal administration, systemic absorption is minimal, with a terminal half-life of 8-12 hours.
Biliary/fecal: ~90% unchanged; renal: <10% (mainly as metabolite).
Miconazole is primarily eliminated via hepatic metabolism with biliary excretion of metabolites; <1% of unchanged drug is excreted renally. Fecal elimination accounts for approximately 20-30% of the dose.
