Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to tubulin, disrupting microtubule function and inhibiting fungal cell mitosis; deposited in keratin precursor cells, making keratin resistant to fungal invasion.
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.
250-375 mg orally once daily or 500-750 mg orally once daily for severe infections.
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.

9-24 hours (mean 15 hours); prolonged in liver disease.
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.
Renal (<1% unchanged); fecal (36% as metabolites); tissue deposition may persist for weeks.
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.
