Terbinafine is an allylamine antifungal agent primarily used for the treatment of dermatophyte infections such as onychomycosis (fungal nail infections) and tinea infections of the skin. It acts by inhibiting squalene epoxidase, a key enzyme in fungal ergosterol synthesis. Terbinafine is approved and widely used today.
Pharmacokinetics
Pharmacokinetic parameters reported in healthy adult volunteers (both sexes), following single and multiple oral doses.
