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.

Abstract

The invention provides an externally applied pharmaceutical composition containing a squalene epoxidase inhibitor and an H1 receptor blocker, which aims at overcoming the defect that the antipruritic effect of the squalene epoxidase inhibitor is non-obvious when being used for treating fungal infection. The pharmaceutical composition provided by the invention has the characteristics of killing fungi and realizing synergistic anti-inflammation and synergistic antipruritic effect, and can significantly improve the symptoms of superficial skin fungal infection.

Description

technical field [0001] The invention belongs to the field of medicine, in particular to an external pharmaceutical composition for treating skin fungus infection. Background technique [0002] Superficial skin fungal infectious diseases account for a high proportion of skin diseases, are generally easy to relapse, and are difficult to cure, and belong to one of the intractable skin diseases. Clinically common skin fungal infectious diseases include tinea manuum, tinea pedis, jock itch, tinea corporis, tinea capitis, etc. The symptoms are mainly manifested in local skin moist flushing, erosion, maceration and whitish or small blisters, unbearable itching of the skin, erysipelas and lymphangitis often caused by secondary infection after scratching, easy keratosis and desquamation after drying, chapped. Can be contagious, easy to relapse. The main causes of skin fungal infections are Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton gypsum, Trichophyton violaceu...
