1. What Sulfasalazine is and what it is used for
Sulfasalazine is an anti-inflammatory drug and belongs to a group of medicines called

doses to prevent more flare-ups of ulcerative colitis.

from the mouth to the anus, but it most commonly affects the last part of the small bowel and
the first part of the large bowel. Symptoms include abdominal pain and diarrhoea (which may
