Mechanism of Action of undefined

Iguratimod's mechanism of action involves suppressing the production of pro-inflammatory cytokines, such as IL-1, IL-6, and TNF-α, which contribute to autoimmune responses and inflammation. It may also modulate T cell activity, downregulate inflammatory mediators like COX-2 and MMPs, and influence immune cell activation, collectively reducing inflammation and mitigating damage caused by autoimmune diseases. Additionally, It's potential antioxidant properties could further contribute to its anti-inflammatory effects.

As a disease-modifying antirheumatic drug (DMARD), this medication helps reduce inflammation, alleviate symptoms, and potentially slow disease progression. While investigational, it is also being explored for other autoimmune conditions like ankylosing spondylitis, psoriatic arthritis, systemic lupus erythematosus, juvenile idiopathic arthritis, and Behçet's disease, indicating its potential broader application in managing various inflammatory and immune-related disorders.
