Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Terbinafine inhibits squalene epoxidase, an enzyme in the fungal ergosterol biosynthesis pathway. This leads to accumulation of squalene and depletion of ergosterol, disrupting fungal cell membrane integrity and causing cell death.
Miconazole inhibits fungal lanosterol 14α-demethylase, a cytochrome P450 enzyme, thereby blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Terbinafine 250 mg orally once daily for 6 weeks for fingernail onychomycosis or 12 weeks for toenail onychomycosis. Topical: 1% cream applied once daily for 1 week for tinea pedis; 1% solution applied once daily for 1 week for tinea corporis/cruris.
Topical: Apply once daily to affected areas for 2-4 weeks. Vaginal: One 200 mg suppository at bedtime for 3 days, or one 100 mg suppository at bedtime for 7 days, or one 1200 mg suppository as a single dose.

The terminal elimination half-life is approximately 11-17 hours in healthy adults; however, it increases to about 200-400 hours in the distribution phase from tissues (e.g., skin, adipose). Steady-state is reached after 10-14 days of oral dosing.
Terminal elimination half-life is approximately 24–30 hours, supporting twice-daily or once-daily dosing for dermatologic infections.
Terbinafine is extensively metabolized in the liver; approximately 80% of a dose is excreted in urine as metabolites, and 20% in feces. Less than 1% is excreted unchanged in urine.
Primarily fecal (biliary) elimination as unchanged drug and metabolites; <1% renal excretion of unchanged drug.
