In several large studies budesonide 2mg rectal foam was found to be effective in the treatment of distal ulcerative colitis. Clinical trials suggest that budesonide foam demonstrates improved reach and rapid distribution of budesonide to the sigmoid colon and the rectum compared to enema formulations. These trials also suggest that the foam provides immediate and targeted therapy for distal ulcerative colitis.

The oral foam formulation for rectal administration was designed to improve both the patient’s ability to retain the drug in the rectum following administration as well as distribution of the active drug to the rectum and sigmoid colon.
