Interleukin inhibitors are a class of medications that target specific proteins called interleukins, which play a crucial role in the immune system. By blocking these proteins, interleukin inhibitors help reduce inflammation and modulate immune responses, making them useful in treating various autoimmune diseases, such as rheumatoid arthritis and psoriasis. These inhibitors can improve symptoms and quality of life for patients by decreasing the overactive immune response that characterizes these conditions. Some common interleukin inhibitors include ustekinumab and secukinumab, which specifically target different interleukins to provide tailored treatment options for individuals.
