I was on oxycontin, now I am on ms contin. Oxycodone is metabolized into noroxycodone and oxymorphone
and some oxycodone remains unmetabolized. As far as pain control goes, ms contin, for me, is highly superior....highly! Again, that is for me. The only reason the high is greater with the oxycontin is because of the high percentage that doesn't get lost in the liver. Also, ms contin lasts a lot longer for me. And, it seems to have a much more soothing effect....especially with the pain.
