Efficacy of Dipotassium Glycyrrhizinate Emollients in the Maintenance Treatment of Adult Atopic Dermatitis
- Conditions
- Adult Atopic Dermatitis
- Interventions
- Drug: White yu green skin lotion
- Registration Number
- NCT06565117
- Brief Summary
To investigate whether emollients containing dipotassium glycyrrhizinate have a sustained improvement in the clinical severity of mild to moderate atopic dermatitis in adult.
- Detailed Description
Atopic dermatitis (atopic eczema, AD) is a common skin inflammatory disease, dry skin and itchy skin is a significant symptom of most AD, often accompany patients for life, seriously affecting the physical and mental health and work life of patients. The number of AD patients is increasing worldwide, while the prevalence rate in China has increased more significantly in the past 10 years. It is characterized by persistent skin dryness and a reduced function of the skin as a barrier to the external environment. Encourage the free use of moisturizers (emollients) as a baseline treatment for AD and add anti-inflammatory therapy as needed. Currently, topical corticosteroids are still the first-line treatment options. However, studies have confirmed that patients with AD are cautious about the use of topical corticosteroids. Maintaining the humidity of the skin and restoring the barrier function of the skin is the basis of the treatment of atopic dermatitis. And studies have shown that regular use of emollients can improve skin hydration, restore the skin barrier, reduce the frequency of attacks, and reduce the use of topical corticosteroids. In patients with AD, daily use of moisturizing emollients enhances the response to topical corticosteroid therapy, reduce percutaneous water loss (TEWL), restore the skin barrier and promote hydration, and can prevent or reduce AD attacks by improving the associated skin barrier defects, prolonging the time between AD episodes. The purpose of this study is to see whether emollients have sustained improvement on the clinical severity of adult atopic dermatitis in maintenance phase.
