Problems solved by technology

[0006] However, since terbinafine hydrochloride and butenafine hydrochloride fundamentally treat local skin fungal infections by killing or inhibiting fungi, this will inevitably relieve symptoms such as local skin itching, skin flushing or redness, especially pruritus symptoms take a long time
Therefore, when the patient's itching is unbearable, the itching cannot be relieved quickly, which affects the quality of life of the patient to a certain extent.
