Description and Uses

Sulfasalazine (brand name Azulfidine in the U.S., Salazopyrin and Sulazine in Europe and Hong Kong) was developed in the 1950s specifically to treat rheumatoid arthritis. It 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 sulfa pyridine and salicylate with an azo bond. It may be abbreviated SSZ.

Sulfasalazine is an anti-inflammatory (gastrointestinal). Sulfasalazine has been used in granulomatous colitis.
