Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Butoconazole nitrate, an imidazole antifungal agent, inhibits fungal cytochrome P450 14α-demethylase, disrupting ergosterol synthesis and increasing fungal cell membrane permeability.
Inhibits fungal cytochrome P450-dependent 14α-demethylase, thereby blocking the conversion of lanosterol to ergosterol, disrupting fungal cell membrane synthesis.
One 100 mg vaginal ovule inserted intravaginally as a single dose.
200 mg orally once daily; for life-threatening infections, can be increased to 200 mg three times daily for first 3 days then twice daily. IV: 200 mg IV every 12 hours for 2 days, then 200 mg IV once daily.

Clinical Note
moderateTerminal elimination half-life is approximately 6-7 days after intravaginal administration, reflecting slow absorption from the vaginal mucosa and prolonged retention in tissues.
Terminal elimination half-life of itraconazole is approximately 24-36 hours after a single dose, but upon chronic dosing, the half-life increases to 34-42 hours due to saturable metabolism. For the active metabolite hydroxyitraconazole, half-life is similar. This prolonged half-life supports once- or twice-daily dosing.
Primarily as unchanged drug in feces via biliary elimination; <1% excreted renally as metabolites.
Itraconazole is extensively metabolized in the liver; the primary route of elimination is fecal (approximately 54% as metabolites, 18% as unchanged drug). Renal excretion accounts for about 35% of the dose, with <1% as unchanged drug. Bilary excretion also contributes.
