I know ER means extended release. I'm on a 10mg Opana and my wife is on a 10mg Opana ER. Is one more potent than the other? How do they make it to extend the release? Thanks for any input!
They both contain oxymorphone as the active ingredient. The regular Opana 10mg releases the whole 10mg at once. The Opana ER 10mg releases the medication over a 12 hour period. The time release mechanism is built into the way the pill is made. Sometime it is in the coating of the pill and sometimes it is the way the pill dissolves. I'm not sure which mechanism Opana uses. That is why it says not to split, chew or crush a long acting pain pill. Altering the pill defeats the time release mechanism allowing all the medication to release at once. Hope this helps some!
