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.
Nystatin binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity and cause leakage of intracellular contents, leading to fungal cell death.
Initial dose: 0.5 mg/kg intravenously once daily, titrated as tolerated to 5 mg/kg once daily.
Topical: Apply 100,000 units/g cream or ointment to affected area twice daily. Oral suspension: 100,000 units/mL; 4-6 mL swish and swallow four times daily for 14 days. Oral tablets: 500,000 units; 1-2 tablets three times daily.

Terminal half-life: 24-48 hours (up to 7 days in hepatic impairment). Long half-life allows once-daily dosing.
Not well-defined due to minimal systemic absorption following oral or topical administration; estimated to be <1 hour in systemic circulation if absorbed.
Biliary/fecal: ~90% unchanged; renal: <10% (mainly as metabolite).
Primarily via feces as unchanged drug; negligible urinary excretion (<1%).
