Here is the easiest way to look at it, (i think?) ...
Percocet has tylenol in it, however, oxycodone
and oxycontin are just straight
percocet, no tylenol. I believe that oxycodone is the generic name for Roxicodone, which is also obviously percocet without the tylenol. Oxycontin and oxycodone are the same thing, EXCEPT oxycodone is a quick release tablet, and oxycontin is a slow release of the same med. Hydrocodone is the ingredient in Vicodin and Lortab.
