Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amphotericin B binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity, leading to leakage of intracellular contents and cell death.
Miconazole inhibits fungal cytochrome P450 14α-demethylase (CYP51), thereby blocking the conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane. This leads to increased membrane permeability and fungal cell death.
Initial dose: 0.5 mg/kg intravenously once daily, titrated as tolerated to 5 mg/kg once daily.
Intravaginal: 1 applicatorful (100 mg) at bedtime for 3 consecutive nights.

Terminal half-life: 24-48 hours (up to 7 days in hepatic impairment). Long half-life allows once-daily dosing.
Terminal elimination half-life is 20-25 hours (intravaginal administration). This long half-life supports a 3-day dosing regimen, maintaining therapeutic concentrations.
Biliary/fecal: ~90% unchanged; renal: <10% (mainly as metabolite).
Renal: approximately 10-20% as unchanged drug; fecal: >50% as metabolites; biliary: minor route. The majority is eliminated via feces as metabolites, reflecting hepatic metabolism and biliary excretion.
