Aliment Pharmacol Ther 2010; 32: 990–999 Summary Background Ulcerative colitis (UC) is a chronic relapsing and remitting idiopathic inflammatory bowel disorder. Aim To evaluate once‐daily mesalamine (mesalazine) granules (MG) for maintenance of remission of UC. Methods Randomized, double‐blind, placebo‐controlled trial of patients ( n = 209 MG, n = 96 placebo) with UC in remission [revised Sutherland Disease Activity Index (SDAI) rectal bleeding = 0, mucosal appearance <2] who took MG 1.5 g or placebo once‐daily for up to 6 months. Primary efficacy endpoint: the percentage of patients who remained relapse‐free at month 6/end of treatment. Relapse was defined as SDAI rectal bleeding score ≥1 and a mucosal appearance score ≥2, a UC flare, or initiation of medication to treat a UC flare. Results The percentage of relapse‐free patients at month 6/end of treatment was higher with MG than placebo (78.9% vs. 58.3%, P < 0.001) in the intent‐to‐treat analysis. Significant differences ( P ≤ 0.025) favouring MG were observed for most secondary endpoints including improvement in rectal bleeding, physician’s disease activity rating, stool frequency, the SDAI at month 6/end of treatment, patients classified as a treatment success and relapse‐free duration. The incidence of adverse events was similar between groups. Conclusions Once‐daily mesalamine (mesalazine) was effective in maintaining remission of UC for 6 months.
