Application
5-Aminosalicylic Acid (5-ASA): A Gastrointestinal Anti-Inflammatory Agent

5-Aminosalicylic acid (5-ASA or mesalazine) is used as a gastrointestinal anti-inflammatory agent. Although the mechanism of action remains unknown exactly, 5-ASA has in vitro and in vivo pharmacologic effects that decrease leukotriene production, scavenge for free radicals and inhibit leukocyte chemotaxis et al. For clinical purposes, amylose, ethyl cellulose or pH-dependent polymers coated 5-ASA are developed and used for drug delivery to the intestinal tract. In addition, sulfasalazine [S0580] is a prodrug of 5-ASA. (The product is for research purpose only.)
