This is what I found:
The difference between Rytary and Crexont is that Crexont beads have additional features that allow for a longer time over which the medication is released and absorbed.

Fridays....if I have anything go wrong, it's on a Friday!

I have also noticed the timing of medical problems is terrible in that they occur on Friday.

Crexant lists anxiety as a possible side effect. Rytary does not.

Only difference I see is that it may be taken with food. C/l can with a very light meal; I can't see a difference.
