    Topical skin anesthetics inhibit the conduction of nerve impulses from sensory nevres, thereby reducing pain and pruritis.

This is achieved by blocking the sodium channels in the nerve cells, preventing the generation and conduction of nerve impulses. As a result, the brain does not receive pain signals, leading to temporary numbness and relief from discomfort. Therefore, the statement is true.

Lichenification is a skin condition characterized by thickened, rough, and itchy patches. These medications work by inhibiting the growth of fungi, which can contribute to the development of lichenification. By reducing the fungal infection, these medications can help alleviate the symptoms and promote healing of the affected skin in dogs.
