1. What Mezavant XL is and what it is used for
Pharmacotherapeutic group: Aminosalicylic acid and similar agents.
Mezavant XL gastro-resistant, prolonged release tablets contain the active substance mesalazine, which is an
anti‑inflammatory drug for the treatment of ulcerative colitis.
Ulcerative colitis is a disease of the colon (large bowel) and rectum (back passage), where the lining of the
gut becomes red and swollen (inflamed) resulting in symptoms of frequent and bloody stools together with
stomach cramps.
When given for an acute episode of ulcerative colitis, Mezavant XL acts through the entire colon and rectum
to treat the inflammation and reduce symptoms. The tablets can also be taken to help prevent reccurrence of
ulcerative colitis.
