What is Cosentyx?

Cosentyx (secukinumab) is a prescription medication used to treat types of plaque psoriasis, psoriatic arthritis, ankylosing spondylitis, enthesitis-related arthritis, hidradenitis suppurativa (HS), and non-radiographic axial spondyloarthritis, which are autoimmune conditions. Cosentyx is a monoclonal antibody that targets interleukin-17A (IL-17A), a protein involved in the inflammatory process. By blocking IL-17A, Cosentyx helps reduce inflammation and related symptoms.

Cosentyx is from the drug class interleukin (IL) inhibitors.

Cosentyx can be given as an injection under the skin (subcutaneous injection) for all conditions or as an intravenous infusion by your HCP for psoriatic arthritis (PsA), ankylosing spondylitis (AS), or non-radiographic axial spondyloarthritis (nr-axSPA). Cosentyx is often given as a weekly dose for the first 4 weeks, then monthly thereafter, however, the dose schedule may vary with age, administration type, or condition being treated.

Cosentyx FDA approval was received on January 21, 2015, for plaque psoriasis, and since then, other autoimmune conditions have been included.

Cosentyx may improve your symptoms, but it may also lower the ability of your immune system to fight infections.

How does Cosentyx work?

In autoimmune conditions, the overactive immune system produces too much IL-17A, a protein that is believed to play a role in inflammation, pain, and damage, which causes the symptoms of these conditions.

The Cosentyx mechanism of action is as an IL-17A blocker. Cosentyx works by targeting and blocking IL-17A, which helps calm down the immune system, reducing inflammation and improving symptoms.
