Cosentyx is a medication that is a member of a group of monoclonal antibody medications that targets a particular protein implicated in inflammatory responses.

How does it work?

  • Cosentyx is an inhibitor of interleukin-17A (IL-17A).
  • It binds to IL-17A, a pro-inflammatory cytokine important in autoimmune diseases such as psoriasis, ankylosing spondylitis, and psoriatic arthritis.
  • Cosentyx inhibits IL-17A’s interaction with cell receptors by attaching to it, lowering the level of inflammation associated with these diseases.1Overview| Researched based study from
