Opana has a long half life, even in immediate release form, such that 6 hour dosing works extremely well
for most patients versus the 4 hour dosing of
oxycodone. Oxymorphone is the metabolite of oxycodone...in other words, the roxicodone that you take is metabolized by the liver into oxymorphone. Given that you can tolerate oxycodone, which metabolizes into oxymorphone, tells me you can probably also tolerate oxymorphone in immediate release form???
