there is generic rowasa, and there is generic colocort. Those are god-sends. Generic colazol was JUST about to be released earlier this year, when the makers made a desperate ploy to get an extension on their patent by supposedly testing the drug on kids. Still, even that doesn't last a year if I remember right, so you'll see the first of the new class of 5-ASAs go generic in 2008.
Oh, man, generic Colazal would be awesome. Can't wait for that!
I bet the availability of that would actually bring down the price of brand-name Asacol, since a lot of people on Asacol (like me) would otherwise try to switch to generic Colazal.
