Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Griseofulvin binds to tubulin and disrupts microtubule function, inhibiting fungal cell division and nucleic acid synthesis.
Miconazole, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, preventing conversion of lanosterol to ergosterol, thereby disrupting fungal cell membrane synthesis.
500 mg orally once daily or 250 mg orally twice daily; for severe infections, 500 mg twice daily or 250 mg three times daily. Maximum daily dose: 1 g. Administer with or after meals.
Intravaginal: one applicatorful (200 mg miconazole nitrate) at bedtime for 7 nights. Also: topical cream (2%) applied to affected area twice daily for 7 days.

Terminal elimination half-life ranges from 6.5 to 9 hours (mean ~7.5 hours) in patients with normal hepatic function; prolonged in hepatic impairment.
Terminal elimination half-life is approximately 24 hours for miconazole after systemic absorption, reflecting slow tissue redistribution and hepatic clearance. After intravaginal administration, systemic absorption is minimal (<1.4%), so half-life is not clinically relevant.
Primarily hepatic metabolism; less than 1% excreted unchanged in urine; approximately 30-50% of a dose is eliminated in feces as metabolites, with minor biliary excretion.
Miconazole is primarily metabolized in the liver; less than 1% of absorbed dose is excreted unchanged in urine. Fecal excretion accounts for approximately 50% of the dose, primarily as metabolites. Biliary excretion is minimal.
