Reporting Groups

Sulfasalazine: Sulfasalazine has been the parent aminosalicylate in use for over 40 years in the treatment of inflammatory bowel disease. The drug is a conjugate of sulfapyridine linked to 5-aminosalicylic acid. In inflammatory bowel disease, the 5-ASA component is the active moiety

Sulfasalazine is a prodrug that consists of sulfapyridine bonded to mesalamine (5-ASA). Sulfasalazine is cleaved by colonic bacterial azo-reductases into sulfapyridine and the 5-ASA moiety. 5-ASA is metabolized to N-acetyl-5-ASA by an enzyme in the intestinal epithelium and the liver and then excreted in the urine as a mixture of free 5ASA and N-acetyl-5-ASA.
