Apriso’s exact mechanism of action (the way the drug works in the body) isn’t known. It’s thought that Apriso may cause your body to produce fewer proteins and activate fewer cells that cause UC inflammation. This can help maintain UC remission.
Mesalamine, the active drug in Apriso, is considered an antioxidant (a substance that can slow down cell damage). But it isn’t clear whether antioxidants help with UC.
