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 fungal cell death.
Miconazole, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, preventing conversion of lanosterol to ergosterol, thereby disrupting fungal cell membrane synthesis.
3-5 mg/kg/day intravenously for systemic fungal infections; for visceral leishmaniasis: 3 mg/kg/day IV on days 1-5, 14, and 21.
Intravaginal: one applicatorful (200 mg miconazole nitrate) at bedtime for 7 nights. Also: topical cream (2%) applied to affected area twice daily for 7 days.

Terminal elimination half-life: approximately 7–10 hours (initial phase), with a prolonged terminal half-life of 100–153 hours due to slow redistribution from tissues; clinically, this supports once-daily dosing after initial accumulation.
Terminal elimination half-life is approximately 24 hours for miconazole after systemic absorption, reflecting slow tissue redistribution and hepatic clearance. After intravaginal administration, systemic absorption is minimal (<1.4%), so half-life is not clinically relevant.
Renal: negligible (<1% unchanged); Biliary/fecal: primary route, approximately 90% of dose recovered in feces as parent drug and metabolites; Urinary: minimal (less than 1% as unchanged drug).
Miconazole is primarily metabolized in the liver; less than 1% of absorbed dose is excreted unchanged in urine. Fecal excretion accounts for approximately 50% of the dose, primarily as metabolites. Biliary excretion is minimal.
