Used in the treatment of autoimmune diseases such as rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, and plaque psoriasis. It works by binding to tumor necrosis factor-alpha (TNF-α), a key mediator of inflammation, thereby inhibiting its pro-inflammatory activity. This reduces inflammation, slows disease progression, and improves symptoms in affected patients. Also used off-label in other inflammatory conditions like uveitis and hidradenitis suppurativa. Administered via subcutaneous injection, it is part of biologic therapy regimens where conventional treatments are insufficient.
