Cosentyx (secukinumab) and Humira (adalimumab) are prescription medications used to treat certain inflammatory conditions. These include plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis.
Both drugs are biologics (drugs made using living cells). They block overactive parts of your immune system, which is your body’s defense against disease. They reduce inflammation and control the symptoms of these conditions.
Cosentyx and Humira are both brand-name drugs. Cosentyx isn’t currently available in a biosimilar form. (A biosimilar is a medication that’s similar to a brand-name biologic drug.) Humira has several biosimilars, but these aren’t yet available in the United States.
