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.
Allylamine antifungal that inhibits squalene epoxidase, an enzyme in the ergosterol biosynthesis pathway, leading to accumulation of squalene and disruption of fungal cell membrane function.
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.
250 mg orally once daily for 2-6 weeks for dermatophyte infections; 250 mg orally once daily for 12 weeks for onychomycosis.

Terminal half-life is approximately 21–24 hours, supporting once-daily or twice-weekly dosing for vaginal candidiasis.
Terminal elimination half-life is approximately 17-24 hours in healthy adults. However, it can prolong to about 36-40 hours in patients with renal or hepatic impairment. The prolonged half-life allows for once-daily dosing. Due to extensive tissue distribution, the functional half-life (terminal phase from tissues) may be longer.
Primarily hepatic metabolism with <5% excreted unchanged in urine; fecal elimination accounts for ~30% of metabolites.
Approximately 70% of the administered dose is excreted in the urine as metabolites, with less than 5% as unchanged drug. About 20% is eliminated via feces. Terbinafine undergoes extensive hepatic metabolism; renal elimination of metabolites is the primary route.
