AMPHOTERICIN B vs MYCOSTATIN
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.
Mycostatin (nystatin) is a polyene antifungal antibiotic that binds to ergosterol in the fungal cell membrane, forming pores that increase membrane permeability, leading to leakage of intracellular contents and cell death.
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.
Nystatin suspension: 400,000-600,000 units (4-6 mL) orally four times daily for 7-14 days. Nystatin pastilles: 200,000-400,000 units (1-2 pastilles) orally four to five times daily for 7-14 days.

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.
Not applicable (nystatin is not absorbed systemically; no meaningful plasma half-life exists). For reference, if absorbed, the terminal half-life would be approximately 4-6 hours, but this is not clinically relevant.
Renal: ~2-5% unchanged; biliary/fecal: ~40% as metabolites; extensive tissue binding delays excretion.
Nystatin is not absorbed from the gastrointestinal tract, skin, or mucous membranes. After oral administration, virtually all of the drug is excreted unchanged in feces. Renal excretion is negligible (<0.1%).
