Asacol 400 mg Tablets are formulated with mesalamine, also known as 5-aminosalicylic acid, which acts locally in the colon to reduce inflammation. The tablets are coated with a pH-sensitive resin that dissolves at pH 7 or greater, ensuring the release of mesalamine in the terminal ileum and beyond for targeted anti-inflammatory action in the colon. This targeted delivery helps alleviate symptoms such as abdominal pain, diarrhea, and rectal bleeding associated with ulcerative colitis. .
