The role of dermatropin is mainly anti-inflammatory, anti-itching, in addition to a certain anti-proliferative effect. Because the main ingredient of dermatophyte is dexamethasone, it is a glucocorticoid topical drug, for chronic eczema, dermatitis and hyperplastic skin disease has a certain therapeutic effect, for acute eczema and dermatitis also has obvious anti-inflammatory, anti-itching effect. In addition, fungal infections and the formation of chronic hyperplastic dermatosis can use dermatophyte topical application, waiting for the hyperplasia to be alleviated after the use of antifungal drug treatment, which can play a more effective effect. However, because the dermatophyte is, after all, a glucocorticoid hormone class of topical drugs, so you can not use long-term and large areas, otherwise it may cause secondary infections, local skin atrophy or capillary dilatation and other side effects.
