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.
Terconazole is a triazole antifungal agent that inhibits fungal cytochrome P450 14α-demethylase, thereby blocking the conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane. This disrupts membrane integrity and function.
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.
Intravaginal cream (0.4%, 0.8%): one applicatorful (approximately 5 g) intravaginally once daily at bedtime for 7 days; vaginal suppository (80 mg): one suppository intravaginally once daily at bedtime for 3 days.

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 25-37 hours, allowing once-daily dosing for vaginal 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 hepatic metabolism with biliary excretion; approximately 60-80% of the dose is excreted in feces as metabolites, and about 20% in urine mostly as inactive metabolites.
