ABSTRACT

Rosacea is a kind of chronic inflammatory skin disease that usually occurs in the middle of the face. Diammonium glycyrrhizinate (DG), an effective monomer component extracted from licorice, has extensive anti-inflammatory, antioxidant, anti-allergic, and immunomodulatory effects. There is no research on its therapeutic effect on rosacea. In this study, we divided rosacea patients mainly characterized by papules and pustules randomly into 3 groups. Group A received clarithromycin 500 mg once a day, isotretinoin 10 mg once a day; Group B received DG 150 mg three times a day, other medicines were the same as Group A; Group C received clarithromycin 250 mg once a day, isotretinoin 10 mg once every two days, and DG 150 mg three times a day. All patients' symptom scores and laboratory tests were evaluated when followed up. We found that DG combined with clarithromycin and isotretinoin in the treatment of rosacea was more effective and quicker than clarithromycin and isotretinoin alone. Moreover, half common dosage of clarithromycin and isotretinoin combined with DG could achieve the same therapeutic effect as the conventional dose, and brought about lower incidences of adverse events (AEs). Therefore, it is recommended to use half common dosage of routine medication combined with DG for rosacea patients mainly characterized by papules and pustules.
