Sulfasalazine (SSZ)

Sulfasalazine was believed at the time that bacterial infections were the cause of rheumatoid arthritis. Sulfasalazine is a sulfa drug, a derivative of mesalazine, and is formed by combining sulfapyridine and salicylate with an azo bond. Sulfasalazine is used in the treatment of inflammatory bowel disease, including ulcerative colitis and Crohn"""s disease. It is also indicated for use in rheumatoid arthritis and used in other types of inflammatory arthritis (e.g. psoriatic arthritis) where it has a beneficial effect. It is often well tolerated compared to other DMARDs. In clinical trials for the treatment of chronic alcoholics, sulfasalazine has been found to reverse the scarring associated with cirrhosis of the liver.[citation needed] Cells called myofibroblasts, which contribute to scar tissue in a diseased liver, also appear to secrete proteins that prevent the breakdown of the scar tissue. Sulfasalazine appears to retard this secretion.
