"Clipper"

We moved to Italy from Canada a few months ago and my daughter with UC has been flaring pretty much since. Her pediatric GI prescribed her an oral steroid called "clipper" which is an entric coated pill for delayed release. It's more locally absorbed and less systemic than pred (though there is still some systemic absorption of course). She takes one 5mg pill where as she would have been on about 16ml of pred. It's been quite effective so far.
Does anyone know WHY this is not available in North America? I guess it's similar to entocourt but I've heard that that is not really effective for UC (more so for CD)? It's not budoniside.
It's very confusing and I'm pretty upset that we have given her two courses of pred in the past when she could have had this if it had been available?
Has anyone else in Europe used this med?

Yes i have used it before passing to classic steroids..and at the beginning it hqs been quite good ...but I live in Italy ...

If you need any advice on the Italian best centrex for UC. Just let me know
