efficacy and safety of tranilast combined with minocycline in the treatment of rosacea

Conditions: Rosacea

Summary: rosacea is a chronic inflammatory skin disease with a complex pathogenesis involving multiple factors. currently, the treatment of rosacea remains highly challenging. mast cells, as key participants in the pathogenesis of rosacea, have been shown to alleviate rosacea symptoms with some topical, oral, and injectable mast cell stabilizers in recent years. tranilast stabilizes mast cells and basophils by acting on their cell membranes and preventing their degranulation. tranilast has been used in the treatment of various skin disease, such as hypertrophic scars and atopic dermatitis. minocycline is a first-line treatment for rosacea, and low-dose minocycline treatment (50mg/day) is believed to have anti-inflammatory effects without antibacterial effects, thus minimizing the dysbiosis and bacterial resistance caused by antibiotic use. therefore, this study aims to investigate the effectiveness and safety of combining mast cell stabilizer tranilast with low-dose minocycline treatment for rosacea, providing new treatment options and insights for rosacea patients.

rosacea is a chronic inflammatory skin disease with a complex pathogenesis involving multiple factors. currently, the treatment of rosacea remains highly challenging. in the skin, mast cells are located in the dermis near nerve endings and blood vessels, playing a crucial role in inflammatory responses. mast cells, as key participants in the pathogenesis of rosacea, have been shown to alleviate rosacea symptoms with some topical, oral, and injectable mast cell stabilizers in recent years. tranilast stabilizes mast cells and basophils by acting on their cell membranes and preventing their degranulation. tranilast has been used in the treatment of various skin disease, such as hypertrophic scars and atopic dermatitis. minocycline is a first-line treatment for rosacea, and low-dose minocycline treatment (50mg/day) is believed to have anti-inflammatory effects without antibacterial effects, thus minimizing the dysbiosis and bacterial resistance caused by antibiotic use. however, there is currently a lack of clinical studies evaluating the efficacy and safety of combined treatment with tranilast and minocycline for rosacea. therefore, this study aims to investigate the effectiveness and safety of combining mast cell stabilizer tranilast with low-dose minocycline treatment for rosacea, providing new treatment options and insights for rosacea patients.
