Interleukin-17 inhibitors are a class of medications designed to block the action of interleukin-17, a protein involved in inflammation and immune responses. These inhibitors are primarily used to treat autoimmune conditions such as psoriasis, psoriatic arthritis, and ankylosing spondylitis, where excessive inflammation leads to tissue damage. By targeting interleukin-17, these drugs help reduce inflammation and alleviate symptoms, improving the quality of life for patients. Common examples of interleukin-17 inhibitors include secukinumab and ixekizumab. They are typically administered through injections and may have side effects, so monitoring by a healthcare provider is essential.
