How does this medication work? What will it do for me?
5-aminosalicylic acid (5-ASA or mesalamine) belongs to the group of medications known as anti-inflammatories. It is used to treat mild to moderate ulcerative colitis and mild to moderate Crohn's disease. 5-ASA acts by reducing inflammation in the bowel.
Different brands of 5-ASA are designed to act on different places in the gastrointestinal tract (the digestion tube that runs from the mouth to the anus). Ulcerative colitis affects the colon and rectum only, while Crohn's disease affects the whole gastrointestinal tract. For this reason, some brands are used to treat only ulcerative colitis, while others can be used to treat both Crohn's disease and ulcerative colitis.
