A comparison of sucralfate and prednisolone enemas in the treatment of active distal ulcerative colitis

Abstract

Sucralfate is well established in the treatment of upper gastrointestinal inflammation and ulceration, and preliminary evidence suggests it may be of benefit in active colitis. We have therefore undertaken a clinical trial to compare enemas of sucralfate (4 g) and prednisolone metasulphobenzoate (20 mg) in the treatment of active distal ulcerative colitis. Forty-four patients were entered into a 4-week study. Two patients were withdrawn because of non-compliance, and five were unable to complete the study: two developed constipation (both allocated to sucralfate) and three were unable to retain the enemas (two prednisolone and one sucralfate). Intention-to-treat analysis showed significant within-treatment improvement in rectal bleeding, sigmoidoscopic grade, and histologic grade in the prednisolone-treated group, and in stool frequency, rectal bleeding, and sigmoidoscopic grade in the sucralfate-treated group. Between-treatment comparisons, however, showed greater resolution of rectal bleeding and more marked improvements in histologic grade in patients treated with prednisolone metasulphobenzoate enemas. Further studies using higher doses of sucralfate would be useful.
