Brodalumab is a medication used to treat moderate to severe plaque psoriasis, a chronic skin condition characterized by red, scaly patches. It works by targeting and blocking a specific protein called IL-17, which plays a key role in the inflammatory process of psoriasis. By inhibiting this protein, brodalumab helps reduce the symptoms and improve the skin's appearance. Administered as an injection, brodalumab is typically prescribed for patients who have not responded well to other treatments. Like all medications, it may have side effects, including an increased risk of infections. Patients should discuss potential risks and benefits with their healthcare provider before starting treatment.
