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 nitrate inhibits fungal lanosterol 14α-demethylase (CYP51), disrupting ergosterol synthesis and causing fungal cell membrane damage.
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.
Intravaginally, one suppository (100 mg miconazole nitrate) once daily at bedtime for 7 days or one suppository (200 mg) once daily for 3 days, combined with topical application of miconazole nitrate cream (2%) to the vulvar 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 20-25 hours, but can be prolonged to 30-40 hours in patients with hepatic impairment.
Primarily renal (as glucuronide conjugates): ~80%; fecal/biliary: ~10-15%; unchanged drug <1%.
Primarily fecal (biliary) as unchanged drug and metabolites (~50-60%); renal excretion accounts for <20% of the dose, mostly as inactive metabolites.
