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.
Inhibition of fungal cell mitosis by binding to microtubules, disrupting spindle formation and nuclear division.
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.
125 mg orally once daily with a high-fat meal for 7 days, then 125 mg every other day for 7 days (total 13 doses).

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 approximately 9.5 hours; may be prolonged in liver disease.
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; <1% excreted unchanged in urine; metabolites excreted in bile and feces.
