Asacol belongs to a group of medications called aminosalicylates. It is thought that the medication works by inhibiting the production of inflammatory chemicals in the lining of the colon. Asacol decreases the production of prostaglandins and leukotrienes, chemicals that lead to the inflammation of ulcerative colitis.
Asacol tablets have a special delayed-release coating. The coating prevents Asacol tablets from dissolving until they reach the very end of the small intestine.
Asacol is approved to treat ulcerative colitis in children age five and older for a six-week course of treatment. It is not yet approved for long-term use to prevent symptoms from returning in children. Be sure to talk with your healthcare provider about the risks and benefits of using Asacol in children.
