Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
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.
Intravaginal administration: 100 mg (one applicatorful of 2% cream) once daily for 3 days; or 100 mg (one suppository) once daily for 3 days; or 5 g (one applicatorful of 4% cream) as a single dose.
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.

Terminal half-life is approximately 21–24 hours, supporting once-daily or twice-weekly dosing for vaginal candidiasis.
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.
Primarily hepatic metabolism with <5% excreted unchanged in urine; fecal elimination accounts for ~30% of metabolites.
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.
