Drug survival of fumaric acid esters for psoriasis

[Caroline]

Which makes it a pretty useless study as there are differences it's like comparing cooking apples to desert apples, one is likely to upset your stomach the other isn't in my opinion

Well exactly this stomach upsetting is clear. That happens with unprotected DMF. Bill is also always taking his measures to get it as fast as possible into the intestines.
I guess most of the different types have stomach protection or delayed release.

By the way, it is always the ester of fumaric acid that is used, we normally name it DMF, but it is in the ester form.
