AMPHOTERICIN B vs FULVICIN P/G
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to ergosterol in fungal cell membranes, forming pores that increase permeability and cause leakage of intracellular contents, leading to cell death.
Binds to microtubule-associated proteins, disrupting mitotic spindle formation and inhibiting fungal cell division.
0.5-1.5 mg/kg/day IV over 2-6 hours; for invasive aspergillosis, 1 mg/kg/day; for cryptococcal meningitis, 0.7 mg/kg/day IV in combination with flucytosine; liposomal formulation: 3-5 mg/kg/day IV. Maximum dose: 1.5 mg/kg/day for conventional amphotericin B deoxycholate.
250 mg orally twice daily for tinea infections; 500 mg orally twice daily for onychomycosis. Administer with a fatty meal to enhance absorption.

Clinical Note
moderateAmphotericin B + Digoxin
"The risk or severity of adverse effects can be increased when Amphotericin B is combined with Digoxin."
Clinical Note
moderateAmphotericin B + Digitoxin
"The risk or severity of adverse effects can be increased when Amphotericin B is combined with Digitoxin."
Clinical Note
moderateAmphotericin B + Deslanoside
"The risk or severity of adverse effects can be increased when Amphotericin B is combined with Deslanoside."
Clinical Note
moderateTerminal half-life: 24–48 hours initially, prolonged to 15 days with repeated dosing due to tissue redistribution.
Terminal elimination half-life: 9–24 hours (mean ~16 hours). Clinical context: prolonged half-life allows once-daily dosing; steady-state achieved within 2–3 days.
Renal: ~2-5% unchanged; biliary/fecal: ~40% as metabolites; extensive tissue binding delays excretion.
Renal (largely unchanged, <1% as metabolites); biliary/fecal (minor). Approximately 36% of a dose is excreted in urine within 6 hours, and up to 50% within 72 hours.
