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.
Inhibits fungal cytochrome P450 (CYP450)-dependent lanosterol 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Intravaginal administration of 100 mg miconazole nitrate suppository once daily at bedtime for 7 days.
200 mg orally twice daily for 3-7 days; for onychomycosis: 200 mg orally once daily for 12 weeks.

Terminal elimination half-life is approximately 24-30 hours following intravaginal administration; clinical significance: supports once-daily dosing.
The terminal elimination half-life of itraconazole ranges from 21 to 35 hours for single doses, increasing to approximately 34 to 42 hours at steady state. The half-life of the active metabolite, hydroxyitraconazole, is similar. This long half-life allows for once-daily or twice-daily dosing in most indications.
Primarily via feces (approximately 87-93% of dose) as unchanged drug and metabolites; renal excretion negligible (<1%).
Itraconazole is extensively metabolized in the liver via CYP3A4 to active metabolites, including hydroxyitraconazole. The parent drug and metabolites are primarily excreted in feces (approximately 54%) and urine (approximately 35%), with less than 1% of the dose excreted unchanged in urine.
