APRISO (mesalamine)

Immunology Approved 2008-10-31

Apriso is an aminosalicylate used for adults who have ulcerative colitis. It helps patients with this condition stay in remission after their initial symptoms have been managed. This medication is prescribed to provide ongoing support for the colon and prevent the return of active disease.

How APRISO Works

This drug works by providing a local anti-inflammatory effect directly on the cells lining the colon. It likely reduces inflammation by blocking the production of specific metabolites, such as prostanoids and leukotrienes, which are typically elevated in patients with ulcerative colitis.
