If you have ulcerative colitis, your healthcare provider may recommend treatment with Asacol® (mesalamine). It belongs to a class of drugs known as aminosalicylates. Asacol comes in the form of delayed-release tablets and is generally taken three times a day.
It is thought that Asacol works by inhibiting the production of inflammatory chemicals in the lining of the colon. This drug decreases the production of prostaglandins and leukotrienes, chemicals that lead to the inflammation that is characteristic of ulcerative colitis.
