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]
History edit
Olsalazine gained Food and Drug Administration (FDA) approval in 1990.
Supply edit
The drug is supplied by UCB Pharma.
Research edit
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]
