Sulfasalazine is a pro-drug (a medication not active in its ingested form) and is mainly used to treat ulcerative colitis (chronic ulceration in the large intestine). Following ingestion, bacteria break this pro-drug down in the colon to form 5-aminosalicylic acid or 5-ASA and sulfapyridine. The chemical substance 5-ASA possesses remedial advantages, but it is still uncertain if sulfapyridine contributes any supplementary therapeutic gain. It may be noted that the inflammation of ulcerative colitis or, for that matter, any other inflammatory disease is partially caused by disproportionate production of certain chemicals, for instance, prostaglandins, which cause swelling and tenderness. Two enzymes - lipoxygenase and cyclooxygenase, are responsible for the production of prostaglandins and these enzymes have been found to be overcharged in people suffering from ulcerative colitis. In effect, 5-ASA is able to lessen the inflammation by means of obstructing the actions of cyclooxygenase and lipoxygenase. This action of 5-ASA, in turn, decreases prostaglandin production. The Food and Drug Administration approved the sale and use of sulfasalazine in 1950.
