Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Griseofulvin binds to and disrupts microtubule function by interfering with the polymerization of tubulin, thereby inhibiting fungal cell mitosis 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.
For tinea capitis and other dermatophyte infections: 500 mg oral daily as a single dose or in divided doses. For more severe infections, up to 1 g daily in divided doses.
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 14-24 hours. With continuous therapy, time to steady-state is ~3-5 days.
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 renal (as glucuronide conjugates): ~80%; fecal/biliary: ~10-15%; unchanged drug <1%.
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.
