title: [Comparative randomized open study of the efficacy and tolerance of enemas with 2 gr of 4-amino-salicylic acid (4-ASA) and 1 gr of 5-amino-salicylic acid (5-ASA) in distal forms of hemorrhagic rectocolitis].
abstract: OBJECTIVE
  The aim of this multicentre, randomized open trial was to compare the efficacy and tolerance of 4-ASA vs 5-ASA enemas in the treatment of distal moderately active ulcerative colitis. Fifty patients were randomized to receive enemas in 100 mL suspension of 4-ASA (2 g, n = 26), or 5-ASA (1 g, n = 24). The subjects filled a daily questionnaire on enema retention duration, and tolerance. Clinical and endoscopic evaluations were performed at baseline and after 2 and 4 weeks.
  
  
  RESULTS
  Significant clinical and endoscopic improvements occurred in both groups. Efficacy and enema retention time did not differ between groups. Tolerance was significantly better for 4-ASA: score 0.46 +/- 0.77 vs 1.00 +/- 0.73, P = 0.03.
  
  
  CONCLUSIONS
  Efficacy of both treatments was equivalent, but 4-ASA enemas were better tolerated than 5-ASA in this open trial.
