BDP and budesonide are locally acting steroid drugs with very low systemic availability and toxicity. Commercially used in the treatment of colitis. Most reasearchers used budesonide for colon delivery, Please comments
I think there are some reports about use of BPD in IBD patients. Problem of bioavailablity is the trick, and beclomethasone was like you wrote, used rarely in studies - but maybe this can help you in some way - see linked publication.
Its very useful review paper. i will study it, However i m still searching any recent reported colinic delivery system loaded with BDP in the therapy of IBD, which i could not find.
