pain
"This Opana is an excellent medication!!  I was taken off of oxycontin 60mg and am now on Opana ER 30 mgs.  They work so much better than the oxycontin for my pain, and the euphoric side effects aren't too bad to boot either.  I would say that a twenty mg opana is equivalent to a forty mg oxy.  The thirties are equivalent to about a sixty plus.  A very good medicine for pain!!"
