I find it really interesting that there is all this talk about the ineffectiveness of 5-ASA's recently. How long have salofalk and pentasa been on the market? I'm thinking since around 1986-88? Is it possible that they are getting close to the end of their patent protection.
Interesting theory, and plausible. Patent protection for drugs is indeed 20 years.
I seem to recall reading a while back that one of the main benefits of taking 5-ASA drugs was to prevent colon cancer, which Crohnies are susectible to.
Sorry to all that I haven´t been active in this forum for awhile, but I´ve been traveling and not always able to get online.
all the best,
