    Product Description

    Balsalazide is a prodrug form of 5-aminosalicylic acid (5-ASA; Item No. 70265).1 It is cleaved by bacterial azoreductases in the intestinal lumen to release 5-ASA. Balsalazide (600 mg/kg per day) decreases IL-2 levels and increases IL-6 levels in the serum and colonic mucosa membrane, as well as decreases micro- and macroscopic colonic damage, in a rat model of colitis induced by 2,4-dinitrochlorobenzene (DNCB).2 Formulations containing balsalazide have been used in the treatment of ulcerative colitis.

    WARNING This product is not for human or veterinary use.
