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 is an imidazole antifungal agent that inhibits the synthesis of ergosterol, a key component of fungal cell membranes, by inhibiting the enzyme lanosterol 14α-demethylase. This leads to increased membrane permeability and leakage of cellular contents, resulting in fungal cell death.
Initial dose: 0.5 mg/kg intravenously once daily, titrated as tolerated to 5 mg/kg once daily.
Miconazole 200 mg vaginal suppository once daily at bedtime for 7 days, plus miconazole 2% cream applied intravaginally once daily at bedtime 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 24-30 hours after systemic absorption. Clinically, this supports once-daily dosing for the vaginal route.
Biliary/fecal: ~90% unchanged; renal: <10% (mainly as metabolite).
Miconazole is primarily metabolized in the liver, with metabolites and unchanged drug excreted in feces (50-70%) and urine (10-20%). Biliary excretion is a minor route.
