Clinical Trial Summary

The treatment of chronic inflammatory skin diseases is a difficult point in clinical diseases, which mainly include patients with pathological scars, sarcoidosis and chronic eczema. Chronic nodular lesions and long-term itching symptoms bring great physical and mental pain to patients. Long-term repeated treatments are required. At present, the most commonly used treatment is intralesional injection of glucocorticoids. Long-term glucocorticoid injections have some side effects, including pain, hypopigmentation, skin atrophy, pigmentation, telangiectasia and menstrual disorders in women. There are a large number of clinical patients who still lack safe and effective drugs, including children, pregnant women, patients with weakened or defective immunity, and even patients with mild inflammatory skin diseases with mainly itching symptoms. The systemic and topical application of antihistamine drugs provides new ideas for the treatment of inflammatory skin. As the most commonly used clinical antihistamine, chlorpheniramine has a long history in the treatment of allergic diseases and can improve the body's inflammatory state. At the same time, the drug has high safety and is suitable for children and pregnant women, or patients with underlying diseases such as hypertension, diabetes, and immunodeficiency diseases.


Clinical Trial Description

At present, there are more and more reports about the application of antihistamines to the treatment of pathological scars. Exposing fibroblasts from normal skin and keloids to the antihistamine diphenhydramine can inhibit the growth of keloid fibroblasts . Based on the existing research foundation in the field and the results of our previous laboratory experiments, we hypothesize that intralesional injection of chlorpheniramine can improve the pruritus symptoms and the severity of skin lesions in inflammatory skin diseases, and can be used as a new application of traditional medicine. ;
