AMPHOTERICIN B vs TERCONAZOLE
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.
Terconazole is a triazole antifungal agent that inhibits fungal cytochrome P450 14α-demethylase, thereby blocking the conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane. This disrupts membrane integrity and function.
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.
Intravaginal cream (0.4%, 0.8%): one applicatorful (approximately 5 g) intravaginally once daily at bedtime for 7 days; vaginal suppository (80 mg): one suppository intravaginally once daily at bedtime for 3 days.

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 approximately 25-37 hours, allowing once-daily dosing for vaginal infections.
Renal: ~2-5% unchanged; biliary/fecal: ~40% as metabolites; extensive tissue binding delays excretion.
Primarily hepatic metabolism with biliary excretion; approximately 60-80% of the dose is excreted in feces as metabolites, and about 20% in urine mostly as inactive metabolites.
