Aminosalicylates are first-choice treatment for mild-to-moderately active ulcerative colitis (UC); however, multi-dosing regimens are inconvenient. To compare the efficacy and safety of once- (OD) vs. twice- (BD) daily prolonged-release mesalazine (Pentasa, Ferring, Saint-Prex, Switzerland) for active mild-to-moderate UC in a

Maintenance therapy with 5-aminosalicylates (5-ASAs) is recommended in patients with quiescent ulcerative colitis (UC), but compliance rates are low. Once-daily dosing may improve adherence, but impact on the relapse of disease activity is unclear as no previous meta-analysis has studied

Mesalazine (mesalamine) (5-ASA) is considered an anti-inflammatory drug for the treatment of inflammatory bowel disease. It is well tolerated by most patients and induces mucosal healing specifically in ulcerative colitis. Besides its anti-inflammatory properties, 5-ASA has been studied for cancer

5-Aminosalicylates (5-ASA) are considered a first-line therapy for inducing and maintaining remission of mild to moderately active ulcerative colitis (UC). When inflammation in UC is limited to the distal colon, 5-ASA can also be administered rectally as a suppository, enema

Patients with long-standing inflammatory bowel disease (IBD) have an increased risk for colorectal carcinoma (CRC). Earlier studies suggest that the severity of inflammation is an independent risk factor for CRC in ulcerative colitis (UC). We investigated the role of histological
