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.
Inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
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 administration: 100 mg (one applicatorful of 2% cream) once daily for 3 days; or 100 mg (one suppository) once daily for 3 days; or 5 g (one applicatorful of 4% cream) as a single dose.

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 half-life is approximately 21–24 hours, supporting once-daily or twice-weekly dosing for vaginal candidiasis.
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).
Primarily hepatic metabolism with <5% excreted unchanged in urine; fecal elimination accounts for ~30% of metabolites.
