Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to ergosterol in fungal cell membranes, forming pores that increase permeability, leading to leakage of intracellular contents and cell death.
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.
IV: 0.25-1 mg/kg/day as a single infusion; for aspergillosis, up to 1.5 mg/kg/day; maximum daily dose 1.5 mg/kg.
250 mg orally once daily for 2-6 weeks for dermatophyte infections; 250 mg orally once daily for 12 weeks for onychomycosis.

Terminal elimination half-life is approximately 15 days (range 10-20 days) after a single dose; with prolonged therapy, a prolonged terminal half-life of up to 15 days reflects slow redistribution from tissue depots.
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 fecal (40-50%) via biliary elimination without metabolism; renal excretion of unchanged drug is minimal (<5% in 24 hours).
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.
