Used primarily in the treatment of inflammatory bowel diseases, particularly ulcerative colitis. It works by delivering an anti-inflammatory agent, mesalamine, directly to the colon, where it reduces inflammation and symptoms such as diarrhea, rectal bleeding, and abdominal pain. The prodrug design ensures targeted release in the large intestine, minimizing systemic absorption and reducing side effects. Commonly prescribed for mild to moderate active ulcerative colitis and for maintaining remission.
