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 is an imidazole antifungal agent that inhibits the synthesis of ergosterol, a key component of fungal cell membranes, by inhibiting the enzyme lanosterol 14α-demethylase. This leads to increased membrane permeability and leakage of cellular contents, resulting in 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.
Miconazole 200 mg vaginal suppository once daily at bedtime for 7 days, plus miconazole 2% cream applied intravaginally once daily at bedtime 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 24-30 hours after systemic absorption. Clinically, this supports once-daily dosing for the vaginal route.
Primarily renal (as glucuronide conjugates): ~80%; fecal/biliary: ~10-15%; unchanged drug <1%.
Miconazole is primarily metabolized in the liver, with metabolites and unchanged drug excreted in feces (50-70%) and urine (10-20%). Biliary excretion is a minor route.
