Cosentyx vs Skyrizi
IL-17 against IL-23 in plaque psoriasis — the two classes that now dominate treatment, differing in how fast they work and how often they are dosed.
At a glance
Key differences
- Different classes. Cosentyx is an IL-17A inhibitor; Skyrizi is an IL-23 inhibitor. They act on different targets in the body.
- How they are taken. Both are given by the intravenous, subcutaneous route.
- Time on the market. Cosentyx was first approved by the FDA in 2015, Skyrizi in 2019. That gives Cosentyx roughly 4 more years of real-world use and long-term safety data.
- Who markets them. Cosentyx is marketed by Novartis; Skyrizi by AbbVie.

How each one works
12.1 Mechanism of Action Secukinumab is a human IgG1 monoclonal antibody that selectively binds to the interleukin-17A (IL-17A) cytokine and inhibits its interaction with the IL-17 receptor. IL-17A is a naturally occurring cytokine that is involved in normal inflammatory and immune responses. Secukinumab inhibits the release of proinflammatory cytokines and chemokines.
12.1 Mechanism of Action Risankizumab-rzaa is a humanized IgG1 monoclonal antibody that selectively binds to the p19 subunit of human IL-23 cytokine and inhibits its interaction with the IL-23 receptor. IL-23 is a naturally occurring cytokine that is involved in inflammatory and immune responses. Risankizumab-rzaa inhibits the release of pro-inflammatory cytokines and chemokines.

Which medicine is right for a given person depends on their diagnosis, other conditions, other medicines, kidney and liver function, pregnancy, and cost or reimbursement — none of which this page knows. Two drugs in the same class are not automatically interchangeable. Never start, stop or switch a prescription medicine on the basis of a web page; that decision belongs to you and your clinician or pharmacist.
