Igura

Iguratimod tablet is indicated for the treatment of rheumatoid arthritis (RA), a common autoimmune disease. It is a synthetic disease-modifying antirheumatic drug (csDMARD) that has also shown promise in treating other rheumatic and autoimmune conditions, including Sjögren’s syndrome, ankylosing spondylitis, and systemic lupus erythematosus (SLE).

Immunomodulatory Effects: Iguratimod works by acting on both T and B lymphocytes to suppress the immune response.

Anti-inflammatory Action: It inhibits the production of pro-inflammatory cytokines, such as TNF-α, IL-1β, IL-6, and IL-17, which contribute to inflammation.

Osteoprotective Activity: Iguratimod promotes bone formation while inhibiting the differentiation and activity of bone-resorbing osteoclasts.
