Prednisolone and budesonide inhibit intestinal epithelial cell restitution and proliferation in vitro. Both processes play a key role in the rapid resealing of the mucosal barrier following intestinal injury. Thus, impaired intestinal epithelial wound healing under corticosteroid therapy in vivo may be caused by inhibition of intestinal epithelial cell restitution and proliferation.
