abstract: BACKGROUND
  Mesalamine provides a new therapeutic approach in treating Crohn's disease.
  
  
  METHODS
  To assess the efficacy and safety of slow-release mesalamine (Pentasa) in maintaining remission in Crohn's disease, 161 patients with inactive disease were randomized to receive either Pentasa (2 g/day) or placebo in a 2-year double-blind, multicenter trial. Two strata were defined according to the duration of their remission: < 3 months (n = 64) or 3-24 months (n = 97), presumed to be high and low relapse risk strata, respectively.
  
  
  RESULTS
  The probability of relapse was higher in the short-remission placebo group than in the three other groups (p < 0.003), showing there was a significant benefit from Pentasa in the high relapse risk stratum. In this stratum, the 2-year on-going remission rate was of 29% +/- 9% and 45% +/- 11% (mean +/- SD) in the placebo and Pentasa groups, respectively. The incidences of side effects were similar in both groups.
  
  
  CONCLUSIONS
  Pentasa (2 g/day for 2 years) is a safe and effective maintenance treatment for Crohn's disease when given within 3 months of achieving remission.
