AMPHOTERICIN B vs GRISACTIN
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 microtubules and disrupts mitotic spindle formation, 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.
500 mg orally once daily or 250 mg orally twice daily for dermatophyte infections.

Terminal half-life: 24–48 hours initially, prolonged to 15 days with repeated dosing due to tissue redistribution.
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 elimination half-life: 9–24 hours (mean ~14 hours). Clinical context: Steady-state achieved in 3–5 days; once-daily dosing is effective due to prolonged half-life.
Renal: ~2-5% unchanged; biliary/fecal: ~40% as metabolites; extensive tissue binding delays excretion.
Renal: <1% as intact drug; fecal: >99% as metabolites (mainly 6-demethylgriseofulvin glucuronide) via bile; negligible biliary excretion of parent compound.
