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
