AMPHOTERICIN B vs CLOTRIMAZOLE
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.
Clotrimazole inhibits fungal cytochrome P450 14α-demethylase, disrupting ergosterol biosynthesis and increasing membrane permeability.
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.
Topical: Apply thin layer to affected area twice daily for 2-4 weeks. Oral troche: 10 mg troche dissolved slowly in mouth 5 times daily for 14 days. Vaginal: One 100 mg suppository intravaginally at bedtime for 7 days, or 200 mg suppository for 3 days, or 500 mg single dose.

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 half-life is approximately 3-6 hours; due to rapid hepatic metabolism and extensive tissue distribution, clinical effects persist longer than plasma levels suggest.
Renal: ~2-5% unchanged; biliary/fecal: ~40% as metabolites; extensive tissue binding delays excretion.
Primarily fecal (biliary) as unchanged drug and metabolites; minimal renal excretion (<1% unchanged).
