it is the coatings, or chemical bonds, or other things that tme the release to ocur in the colon and not the gut or small intestine that distinguish the name brands. In some cases the ph of the gut is used to cut a chemical bond, or disolve a coating, in one case the bacteria of the colon are used to release the drug.
But the main thing about Lialda is the sponge/matrix aspect of the delivery system that allows for 1x daily dosing. If you did nto hav ethis matrix with this coating, I would take a lower does of generic more times thorught the day. I would not take several 1.2g generic tablets all at once.
