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 nitrate inhibits fungal lanosterol 14α-demethylase (CYP51), disrupting ergosterol synthesis and causing fungal cell membrane damage.
Initial dose: 0.5 mg/kg intravenously once daily, titrated as tolerated to 5 mg/kg once daily.
Intravaginally, one suppository (100 mg miconazole nitrate) once daily at bedtime for 7 days or one suppository (200 mg) once daily for 3 days, combined with topical application of miconazole nitrate cream (2%) to the vulvar area twice daily for 7 days.

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 approximately 20-25 hours, but can be prolonged to 30-40 hours in patients with hepatic impairment.
Biliary/fecal: ~90% unchanged; renal: <10% (mainly as metabolite).
Primarily fecal (biliary) as unchanged drug and metabolites (~50-60%); renal excretion accounts for <20% of the dose, mostly as inactive metabolites.
