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 nitrate inhibits fungal lanosterol 14α-demethylase (CYP51), disrupting ergosterol synthesis and causing fungal cell membrane damage.
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.
Intravaginally, one suppository (100 mg miconazole nitrate) once daily at bedtime for 7 days or one suppository (200 mg) once daily for 3 days, combined with topical application of miconazole nitrate cream (2%) to the vulvar 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 20-25 hours, but can be prolonged to 30-40 hours in patients with hepatic impairment.
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.
Primarily fecal (biliary) as unchanged drug and metabolites (~50-60%); renal excretion accounts for <20% of the dose, mostly as inactive metabolites.
