Quick Summary

Terbinafine is a synthetic antifungal drug belonging to the allylamine group. It works by inhibiting the synthesis of ergosterol, a crucial component of fungal cell membranes.1

Terbinafine is effective in treating fungal infections, particularly those caused by dermatophytes, which are fungi that infect the skin, hair, and nails. It can be used both topically and orally. Oral terbinafine is specifically used for treating nail infections caused by dermatophytes. Other major groups of antifungal drugs include polyenes and azoles, each with distinct chemical structures and mechanisms of action.1
