The active substance in Inflectra, infliximab, is a monoclonal antibody. A monoclonal antibody is an antibody (a type of protein) that has been designed to recognise and attach to a specific structure (called an antigen) in the body. Infliximab has been designed to attach to a chemical messenger in the body called tumour necrosis factor alpha (TNF-alpha). This messenger is involved in causing inflammation and is found at high levels in patients with the diseases that Inflectra is used to treat. By blocking TNF-alpha, infliximab improves the inflammation and other symptoms of the diseases.
