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 inhibits fungal lanosterol 14α-demethylase, a cytochrome P450 enzyme, thereby blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
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.
Topical: Apply once daily to affected areas for 2-4 weeks. Vaginal: One 200 mg suppository at bedtime for 3 days, or one 100 mg suppository at bedtime for 7 days, or one 1200 mg suppository as a single dose.

Terminal elimination half-life 14-24 hours. With continuous therapy, time to steady-state is ~3-5 days.
Terminal elimination half-life is approximately 24–30 hours, supporting twice-daily or once-daily dosing for dermatologic infections.
Primarily renal (as glucuronide conjugates): ~80%; fecal/biliary: ~10-15%; unchanged drug <1%.
Primarily fecal (biliary) elimination as unchanged drug and metabolites; <1% renal excretion of unchanged drug.
