Canasa is a drug that is used to treat ulcerative colitis. It does this by blocking the action of substances that cause inflammation in the colon. Canasa does not cure ulcerative colitis, but only helps in treating the symptoms. It does reduce the amount of stool, the amount of mucus/blood in the stool as well as bleeding that is a result of rectal irritation.
Canasa is a medicine used in the treatment of ulcerative colitis. More specifically, Canasa is used to both treat and prevent the symptoms of ulcerative colitis, proctitis, and proctosigmoiditis. The active ingredient of Canasa - mesalazine - works by reducing the production of pro-inflammatory mediators in the body. By reducing these factors, the relapse rate of ulcerative colitis reduces.
Canasa is available as a rectal preparation, and the drug is not to be administered via the oral route. There are significant potential side effects with Canasa. These include acne, mild rash, nausea, vomiting, rectal pain, and dizziness. Some patients do, however, more severe side effects such as vomiting and chest pain.
