What PENTASA is and what it is used for

The name of this medicine is Pentasa Suppositories. Each suppository
contains mesalazine 1g as the active ingredient. Mesalazine belongs
to a group of medicines called salicylates.
Pentasa is used to treat inflammation in the gut caused by conditions
such as ulcerative colitis. Sometimes ulcerative colitis only affects the
back passage (rectum), this is known as ulcerative proctitis. Pentasa
suppositories are used to treat ulcerative proctitis and are intended for
rectal use only.

The suppositories release the active ingredient slowly which then acts
locally to reduce the inflammation and help relieve or stop the pain.
