Inflammatory bowel disease: current therapeutic options.

Medical management of inflammatory bowel diseases (IBD) includes two treatment strategies: induction and maintenance of remission. 5-Aminosalicylates are mostly used for mild active IBD and for maintenance treatment in ulcerative colitis (UC). Glucocorticoids remain, despite their frequent (and occasionally severe) side effects, as the mainstay for induction of remission in moderate to severe active IBD, both UC and Crohn's disease (CD). Cyclosporine and infliximab have emerged as the main, rapid-acting, alternatives in steroid-refractory UC and CD, respectively. Thiopurines (azathioprine and 6-mercaptopurine) are the most efficient and used immunomodulators in IBD; steroid refractoriness, steroid dependency, and long-term maintenance of remission for both UC and CD are their main indications. Methotrexate and infliximab may be used in the same clinical settings as thiopurines in CD, but not in UC; however, these drugs are a second-line treatment because of safety profile and economic costs.
