Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, preventing conversion of lanosterol to ergosterol, thereby disrupting fungal cell membrane synthesis.
Nystatin binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity and cause leakage of intracellular contents, leading to fungal cell death.
Intravaginal: one applicatorful (200 mg miconazole nitrate) at bedtime for 7 nights. Also: topical cream (2%) applied to affected area twice daily for 7 days.
Topical: Apply 100,000 units/g cream or ointment to affected area twice daily. Oral suspension: 100,000 units/mL; 4-6 mL swish and swallow four times daily for 14 days. Oral tablets: 500,000 units; 1-2 tablets three times daily.

Terminal elimination half-life is approximately 24 hours for miconazole after systemic absorption, reflecting slow tissue redistribution and hepatic clearance. After intravaginal administration, systemic absorption is minimal (<1.4%), so half-life is not clinically relevant.
Not well-defined due to minimal systemic absorption following oral or topical administration; estimated to be <1 hour in systemic circulation if absorbed.
Miconazole is primarily metabolized in the liver; less than 1% of absorbed dose is excreted unchanged in urine. Fecal excretion accounts for approximately 50% of the dose, primarily as metabolites. Biliary excretion is minimal.
Primarily via feces as unchanged drug; negligible urinary excretion (<1%).
