Delzicol (Mesalamine) is a member of the aminosalycilate family of drugs commonly used to reduce inflammation and swelling. Delzicol is specifically targeted to reduce inflammation in the colon and colon to help alleviate symptoms of ulcerative colitis.

Delzicol is a specialized anti-inflammatory drug protected by a PH-sensitive outer shell that prevents the active ingredient 5-aminosalicylic acid (5-ASA) from being broken down and absorbed by the body in the upper GI. The drug’s enteric coating is specifically designed to break down at the PH level found in the terminal ileum (the last section of the small intestine), allowing the drug to deliver its full payload to the large intestine and colon cells.

Delzicol is most commonly prescribed to help reduce or eliminate the diarrhea, irritation, colon or rectal bleeding, and cramping symptoms often associated with ulcerative colitis and other GI disorders.
