Current pharmacotherapy for inflammatory bowel disease.
Ulcerative colitis (UC) and Crohn's disease (CD), collectively termed inflammatory bowel disease (IBD), are chronic spontaneously relapsing enteropathies of unknown aetiology. Pharmacotherapy for IBD has essentially been unchanged for over twenty years, with therapy based around 5-aminosalicylic acid (5-ASA) preparations, corticosteroids, antibiotics and immunosuppression. Much of the controversy surrounding optimal use of these drugs in IBD arises as a consequence of methodological deficiencies in many of the early trials combined with the difficulty in consistent patient selection due to the heterogeneous nature of both UC and CD. More recently, well-designed clinical trials have attempted to provide an 'evidence based' approach to managing IBD which, in time, will allow optimisation of current therapies and accurate evaluation of novel agents. Over the past two decades, improved research methodology has considerably increased our molecular understanding of the aetiopathogenesis of IBD which has ultimately lead to the development of specific mediator directed or 'designer' drug therapy for IBD. This review evaluates the literature on current IBD therapy, summarises the important recent studies which have made an impact on clinical practice, and examines the risks and benefits of the novel agents which are currently under investigation in clinical trials of IBD therapy.
