FEMSTAT 3 vs GRISEOFULVIN, ULTRAMICROSIZE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Butoconazole nitrate, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, preventing ergosterol synthesis and disrupting fungal cell membrane integrity.
Binds to tubulin, disrupting microtubule function and inhibiting fungal cell mitosis; deposited in keratin precursor cells, making keratin resistant to fungal invasion.
Intravaginal cream: 1 applicatorful (5 g of 2% butoconazole nitrate) intravaginally at bedtime for 3 consecutive days.
250-375 mg orally once daily or 500-750 mg orally once daily for severe infections.

The terminal elimination half-life of butoconazole following topical vaginal administration is approximately 21-24 hours. This prolonged half-life supports once-daily dosing for 3 days in the treatment of vulvovaginal candidiasis.
9-24 hours (mean 15 hours); prolonged in liver disease.
Following topical vaginal administration of butoconazole nitrate, approximately 5% of the dose is absorbed systemically. The absorbed fraction is primarily metabolized in the liver and excreted via the biliary/fecal route. Renal excretion accounts for less than 3% of the administered dose.
Renal (<1% unchanged); fecal (36% as metabolites); tissue deposition may persist for weeks.
