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 prodrug 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]

History

Olsalazine gained Food and Drug Administration (FDA) approval in 1990.

Supply

The drug is supplied by UCB Pharma.

Research

In 2006 the Australian biotech company Giaconda received a European patent for a combination therapy for treating constipation-predominant irritable bowel syndrome that uses olsalazine and the anti-gout drug colchicine, for trials the following year.[5]
