Efficacy and safety of mesalamine 1 g HS versus 500 mg BID suppositories in mild to moderate ulcerative proctitis: a multicenter randomized study.

Background: Ulcerative proctitis (UP) usually presents as fresh rectal bleeding. Successful treatment using topical mesalamine 5-aminosalicyclic acid (5-ASA) 500 mg BID suppository led to developing a once-a-day formulation that could contribute to better acceptability and ease of use by patients. The objective of this randomized trial, conducted in 18 centers, was to compare efficacy of 2 modes of treatment with 5-ASA suppositories.
