My understanding is that the Uceris foam goes at least into the sigmoid colon. All of the other foams are rectum-only within the USA. So Uceris foam is the furthest reaching foam available here.
"UCERIS rectal foam is a prescript
ion corticosteroid medicine used to help get active, mild to moderate ulcerative colitis that extends from the rectum to the sigmoid colon
under control (induce remission)."
