Ixekizumab is a medication used to treat moderate to severe plaque psoriasis and active psoriatic arthritis. It is a type of biologic drug that works by targeting and inhibiting a specific protein in the immune system called interleukin-17A, which plays a key role in inflammation and skin cell growth. Administered through injections, Ixekizumab helps reduce the symptoms of these conditions, improving skin appearance and joint function. Patients typically receive an initial dose followed by maintenance doses, depending on their response to the treatment. Regular monitoring by a healthcare provider is essential to ensure safety and effectiveness.
