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, thereby blocking the conversion of lanosterol to ergosterol, a key component of the fungal cell membrane. This disrupts membrane integrity and leads to fungal cell death. Miconazole also has direct anti-inflammatory and antibacterial properties.
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 nitrate 1200 mg vaginal suppository inserted intravaginally once at bedtime; plus external miconazole nitrate 2% cream applied to affected area twice daily for up to 7 days.

Terminal elimination half-life 14-24 hours. With continuous therapy, time to steady-state is ~3-5 days.
Terminal elimination half-life: 24-30 hours (range 20-50 hours). Clinical context: Once-daily dosing may be considered for some indications, but prolonged half-life supports weekly or twice-weekly regimens for systemic infections.
Primarily renal (as glucuronide conjugates): ~80%; fecal/biliary: ~10-15%; unchanged drug <1%.
Fecal: Approximately 90% of absorbed dose; Renal: <2% as unchanged drug; Biliary: Minor, less than 10%.
