Answer

All of the aminosalicylates are useful for treating flares of IBD and for maintaining remission. None of the aminosalicylates has been proven to have greater efficacy than any of the others for the treatment of ulcerative colitis. As a class, these agents appear to be more effective in persons with ulcerative colitis than in persons with Crohn disease; in persons with mild Crohn disease, the primary utility is for colonic disease (as is the case with sulfasalazine [1] ; administer folic acid if sulfasalazine is used). Aminosalicylates have only a weak effect in preventing recurrence after surgery in patients with Crohn disease. [85]

For patients in remission from distal ulcerative colitis, oral or rectal 5-ASA can be used to manage this disease, as well as a combination regimen of oral and topical 5-ASA. [1] In treating rectal disease, rectal 5-ASA is preferred over rectal steroids. [1] A dose response has been described regarding the use of these agents for ulcerative colitis. For moderate disease, a dose of 4.8 g/day of mesalamine has been shown to be more efficacious than 2.4 g/day. [86]
