Initial standard medical treatment for inflammatory bowel disease (IBD) includes a 5-aminosalicylic acid (5-ASA) compound (oral, local or combined) and corticosteroids (oral, local or combined). In both ulcerative colitis and Crohn's disease 5-ASA has proved effective in the acute phase of the disease. As maintenance treatment, it is effective in ulcerative colitis and in some instances also in Crohn's disease. ⋯ These drugs are therefore not of value for treatment in the acute phase of the disease. 6-Mercaptopurine or azathioprine can be used best in combination with steroids in situations where dose reduction of the latter drug repeatedly leads to relapse. They have therefore a steroid-sparing effect and initiate cessation of the long-term severe side-effects of steroids. Another possibility is the use of methotrexate in patients with refractory ulcerative colitis or Crohn's disease.
