By making money with a patent? :0 A lot of the XRs, etc are patent extenders, there is some reason for certain formulations of agents though, like the extended Wellbutrin formulations tend to lower seizure problems.
Basically, the pill is made with multiple coatings I imagine, the first meant not to be breached as much by the hydrochloric acid in the stomach, which would be about a few hours I imagine, and slow the movement through the digestive tract and the blood-brain barrier...
