Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
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 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.
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.

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.
Not well-defined due to minimal systemic absorption following oral or topical administration; estimated to be <1 hour in systemic circulation if absorbed.
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.
Primarily via feces as unchanged drug; negligible urinary excretion (<1%).
