1. WHAT ASACOL 400MG MR TABLETS ARE ANDWHAT THEY ARE USED FOR
Asacol 400mg MR tablets contain the active substance mesalazine (also known as 5-aminosalicylic acid) which is an anti-inflammatory drug used in the treatment of:
- Ulcerative colitis - a disease of the large bowel (colon) and back passage (rectum) in which the lining of the bowel becomes inflamed (red and swollen). Symptoms can include rectal bleeding, frequent diarrhoea and abdominal pain. Asacol 400mg MR tablets act locally in the colon to reduce inflammation and can also prevent further episodes (flares) of ulcerative colitis.
- Crohn’s ileo-colitis – a disease affecting the small bowel (terminal ileum) and colon in which the lining of the bowel becomes swollen and sore. This may lead to the development of ulcers, abscesses and narrowing (strictures) in the bowel. Asacol 400mg MR tablets act locally in the terminal ileum and colon to control the disease and prevent further flares of Crohn’s ileocolitis.
