What generic brands of Oxycontin are available?

Unfortunately, Oxycontin does not come in generic form, and it's timed released action is patented and very expensive. Well that is not entirely correct as Oxycontin is not the only time released version of oxycodone, it does however have it's own patented release compound. Put this way lots of pharmacies will fill an Oxycontin RX with a generic time released oxycodone ...a similar sized pill of similar color per dose. In fact at one recent point there was generic owned by Purdue because all the other generics had stopped. Now all the sudden some ar back again it is crazy! Plus I hear from reliable sources that Oxycontin is now radically changed, the new ones even look new as they show the initials "OP" rather than "OC" on the new tablets I suppose the OP stands for oxycodone/purdue but unlike the originals, supposedly these new ones simply can not be abused in the ways the originals were (ie injected or snorted) I read they are now compounded in a gooey base that can't be crushed into a powder. It remains to be seen I suppose what happens to the generics still fighting to hang on. I can see the feds making the new "OP" pills the gold standard for anti abuse and force the generics into meeting a new spec or else face extinction. That is just a shame for patients that can not afford the brand name or even their share of the brand name if their RX provider caps off at a level well under that price! I can't see Purdue being granted a monopoly on this. It's an old drug well past the patent's expiration I'm sure, the only patent in play is the time release compound. How hard can it be to come up with more versions of a time release anti abuse gimicks ...maybe not even a goo? Perhaps a binary compound where a drug destroying agent sits harmlessly in embedded micropellets that will pass on through a person's digestive tract as long as the pill is swallowed as designed, but should anyone try crushing, heating, or grinding and the destructive agent is released all over the narcotic and instantly ruins it! Wll one of the generics already had a version that was way tougher to abuse than anything else, so much so that just like the new OP pills there were immediatly lots of complaints that not only could the drug not be separated for abuse, but that it also was not working well at all! The theory was too much stayed in compound instead of getting into the bloodstreams of legitimate patients! So now what? Patients will have to get dose increases to make up for these improved drugs inability to release 100% of the intended dose? More half baked ideas?
