GENERIC NAME: terbinafine

BRAND NAME: Lamisil, Lamisil AT

DRUG CLASS AND MECHANISM: Terbinafine is an antifungal agent that is taken by mouth or applied to the skin. Terbinafine acts by interfering with the ability of fungi to make chemicals called sterols that are an important part of the membrane that surrounds fungal cells and holds them together. This weakens the cell membrane. Oral terbinafine is more effective for treating fungal nail infections than griseofulvin (Fulvicin; Gris-Peg) and itraconazole (Sporanox), two other antifungal agents used for treating fungal nail infections. Topical terbinafine was approved by the FDA in 1993. Terbinafine oral tablets were approved in 1996.
