Terbinafine 500 mg Tablet is a high-strength antifungal medication used to treat severe or resistant fungal infections of the skin, nails, and scalp. It belongs to the allylamine class and works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes. This leads to the death of the fungal cells, effectively clearing the infection.
