Mesalamine is used for which condition?

• A. Treating IBS
• B. Treating inflammatory bowel disease (Crohn's and ulcerative colitis)
• C. Treating hepatic disease
• D. Treating pancreatitis

Answer: (B)

Mesalamine is a 5-aminosalicylic acid anti-inflammatory used to treat inflammatory bowel disease, especially ulcerative colitis. It works by delivering anti-inflammatory effects directly to the colonic mucosa, dampening inflammatory mediators like prostaglandins, leukotrienes, and cytokines to reduce mucosal inflammation. This localized action in the colon makes it particularly effective for ulcerative colitis and can help in Crohn's disease when there is colonic involvement. It is not a therapy for irritable bowel syndrome, which is not driven by mucosal inflammation, nor is it used for hepatic disease or pancreatitis, which require different approaches.
