How Does Actemra Work?

Actemra is an antibody that binds to a specific set of receptors known as interleukin-6 (IL-6) receptors in the body. This action prevents the interleukin-6 (which is a natural inflammatory protein) from binding to the receptor, thereby reducing the symptoms of rheumatoid arthritis and juvenile idiopathic arthritis.
Because Actemra targets a specific part of the immune system (IL-6), it is called a "biological response modifier," as it changes (modifies) the body's immune response. It is also known as a "biologic" medication, because it is a protein. Lastly, Actemra is also classified as a monoclonal antibody. Monoclonal antibodies (synthetic antibodies made in a laboratory) are a diverse group of medications used to treat a wide variety of conditions.
