1. What is Pentasa and what is it used for
Pentasa sachets are indicated for the treatment of mild to moderate ulcerative colitis flare-ups and to help maintain you free of further flare-ups.
Ulcerative colitis is an inflammatory bowel disease in which the lining of the intestine is inflamed and develops many small breaks in its surface (ulcers) that can bleed.
Pentasa sachets contain granules that slowly release the active substance (mesalazine). This helps to reduce inflammation and painful symptoms.
