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, reducing ergosterol synthesis and disrupting fungal cell membrane integrity. Tioconazole, also an imidazole, similarly inhibits ergosterol 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 of 6.5% miconazole nitrate cream (1200 mg) at bedtime as a single dose. Topical: Apply 2% miconazole nitrate cream to affected area twice daily for 2 weeks.

Terminal elimination half-life 14-24 hours. With continuous therapy, time to steady-state is ~3-5 days.
The terminal elimination half-life of miconazole following intravenous administration is approximately 24 hours (range 20-30 hours). This supports once-daily dosing for systemic infections, though topical application yields negligible systemic absorption.
Primarily renal (as glucuronide conjugates): ~80%; fecal/biliary: ~10-15%; unchanged drug <1%.
Approximately 90% of an absorbed dose is eliminated in feces as unchanged drug and metabolites; less than 1% is excreted renally as unchanged drug. Biliary excretion is the primary route for the absorbed fraction.
