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 cytochrome P450 14α-demethylase (CYP51), thereby blocking the conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane. This leads to increased membrane permeability and fungal cell death.
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: 1 applicatorful (100 mg) at bedtime for 3 consecutive nights.

Terminal elimination half-life 14-24 hours. With continuous therapy, time to steady-state is ~3-5 days.
Terminal elimination half-life is 20-25 hours (intravaginal administration). This long half-life supports a 3-day dosing regimen, maintaining therapeutic concentrations.
Primarily renal (as glucuronide conjugates): ~80%; fecal/biliary: ~10-15%; unchanged drug <1%.
Renal: approximately 10-20% as unchanged drug; fecal: >50% as metabolites; biliary: minor route. The majority is eliminated via feces as metabolites, reflecting hepatic metabolism and biliary excretion.
