1. What Pentasa is and what it is used for
The name of this medicine is Pentasa slow release tablets. Each tablet contains
mesalazine 1 g as the active ingredient. Mesalazine belongs to a group of
medicines called salicylates.
Pentasa is used to treat mild to moderate inflammation of the gut caused by a

prevent it from coming back.
The tablets release the active ingredient slowly which then acts locally to reduce the
inflammation and help relieve or stop the pain.
