IL-17 inhibitors are a class of medications designed to block the action of interleukin-17, a protein involved in inflammation and immune responses. These drugs are primarily used to treat autoimmune conditions such as psoriasis, psoriatic arthritis, and ankylosing spondylitis. By inhibiting IL-17, they help reduce inflammation and alleviate symptoms associated with these diseases. These medications can improve skin lesions, joint pain, and overall quality of life for patients. Common examples of IL-17 inhibitors include secukinumab and brodalumab. While generally well-tolerated, they may have side effects, so monitoring by healthcare professionals is essential.
