AMPHOTERICIN B vs GRISEOFULVIN
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 microtubular protein tubulin, disrupting mitotic spindle formation and inhibiting fungal cell mitosis. Also interferes with fungal nucleic acid synthesis and cell wall deposition.
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.
500 mg orally once daily or 250 mg orally twice daily; microsize formulation: 500-1000 mg orally once daily; ultramicrosize formulation: 330-375 mg orally once daily. Administer with fatty meal to enhance absorption.

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 is 9 to 24 hours; clinically, it allows once or twice daily dosing.
Renal: ~2-5% unchanged; biliary/fecal: ~40% as metabolites; extensive tissue binding delays excretion.
Primarily hepatic metabolism; less than 1% excreted unchanged in urine; metabolites excreted in urine (approximately 50%) and feces (approximately 36%) within 24 hours.
