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 is an imidazole antifungal agent that inhibits the synthesis of ergosterol, a key component of fungal cell membranes, by inhibiting the enzyme lanosterol 14α-demethylase. This leads to increased membrane permeability and leakage of cellular contents, resulting in fungal cell death.
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.
Miconazole 200 mg vaginal suppository once daily at bedtime for 7 days, plus miconazole 2% cream applied intravaginally once daily at bedtime 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 24-30 hours after systemic absorption. Clinically, this supports once-daily dosing for the vaginal route.
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, with metabolites and unchanged drug excreted in feces (50-70%) and urine (10-20%). Biliary excretion is a minor route.
