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, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, reducing ergosterol synthesis and disrupting fungal cell membrane integrity. Tioconazole, also an imidazole, similarly inhibits ergosterol synthesis.
Initial dose: 0.5 mg/kg intravenously once daily, titrated as tolerated to 5 mg/kg once daily.
Intravaginal: One applicatorful of 6.5% miconazole nitrate cream (1200 mg) at bedtime as a single dose. Topical: Apply 2% miconazole nitrate cream to affected area twice daily for 2 weeks.

Terminal half-life: 24-48 hours (up to 7 days in hepatic impairment). Long half-life allows once-daily dosing.
The terminal elimination half-life of miconazole following intravenous administration is approximately 24 hours (range 20-30 hours). This supports once-daily dosing for systemic infections, though topical application yields negligible systemic absorption.
Biliary/fecal: ~90% unchanged; renal: <10% (mainly as metabolite).
Approximately 90% of an absorbed dose is eliminated in feces as unchanged drug and metabolites; less than 1% is excreted renally as unchanged drug. Biliary excretion is the primary route for the absorbed fraction.
