How Does Terbinafine Work?
As an antifungal medication, terbinafine works by killing the fungus that causes infection. Terbinafine creates holes in the cell membrane of the fungus in order to kill them. Like other medications of its class, terbinafine inhibits squalene epoxidase, an enzyme that catalyzes the conversion of squalene to lanosterol. This helps to destroy the fungal infection by preventing fungus from procreating and spreading.
