Olsalazine is an anti-inflammatory medication used in the treatment of ulcerative colitis.[2][3] It is sold under the brand name Dipentum.[4]

Olsalazine itself is a pro-drug of mesalazine (5-aminosalicyclic acid or 5-ASA) and is not absorbed in the small intestine. Instead it continues through to the colon where it is cleaved into two molecules of 5-ASA by azoreductases produced by colonic bacteria. Olsalazine thus exerts its anti-inflammatory effect by its colonic breakdown into 5-ASA which inhibits cyclooxygenase and lipoxygenase thereby reducing prostaglandin and leukotriene production.[4]
