Overview
Terbinafine is an antifungal medication commonly used in veterinary medicine to treat fungal infections in pets, particularly dogs and cats. It is effective against a variety of fungal pathogens and is widely prescribed by veterinarians.

Terbinafine works by inhibiting the enzyme squalene epoxidase, which is essential in the biosynthesis of ergosterol, a vital component of fungal cell membranes. This disruption leads to the accumulation of squalene, which is toxic to fungi, thereby killing the fungal cells.
