Balsalazide Disodium is an aminosalicylate pharmaceutical active ingredient used in the treatment of ulcerative colitis. It is a prodrug that is converted in the colon to 5-aminosalicylic acid (5-ASA), the pharmacologically active component responsible for its local anti-inflammatory effects.
Balsalazide Disodium is designed to deliver 5-ASA directly to the colon, where it helps reduce inflammation associated with ulcerative colitis.
Balsalazide Disodium is used as an active ingredient in pharmaceutical formulations for the treatment of mild to moderate active ulcerative colitis.
After oral administration, balsalazide reaches the colon, where bacterial azoreductases cleave the azo bond and release 5-aminosalicylic acid (5-ASA).
Balsalazide itself functions primarily as a colon-targeted prodrug. Colonic bacteria metabolize balsalazide to produce:
This colon-specific conversion enables delivery of 5-ASA to the site of inflammation.
