SUMMARY BackgroundInfliximab is a chimeric monoclonal antibody to tumour necrosis factor alpha (TNFa) with efficacy in inducing and maintaining remission of inflammatory bowel disease, rheumatoid arthritis, ankylosing spondylitis and psoriasis. Infliximab is generally administered over 2 h with a further 1-h postinfusion observation. This time interval has substantial impact on healthcare resources and is costly in terms of patient's time away from work.
