What Kyntheum is and what it is used for

Kyntheum is a medicine that contains the active substance brodalumab. Brodalumab is a monoclonal antibody, a special type of protein that recognizes and attaches to certain proteins in your body.

Brodalumab belongs to a group of medicines called interleukin (IL) inhibitors. This drug works by blocking the activity of IL-17 proteins, which occur in elevated levels in diseases such as psoriasis.

Kyntheum is used to treat a skin disease called plaque psoriasis, which causes inflammation and scaly plaque formation in the skin. Kyntheum is used in adults with moderate to severe plaque psoriasis that affects large areas of the body.

The use of Kyntheum will improve skin healing and reduce the signs and symptoms of psoriasis, such as itching, redness, scaling, burning, tingling, cracking, flaking, and pain.
