oxycodone is the active ingredient in
percocet...the reason that
oxycontin is so much more expensive is the amount of milligrams, most percs are 5mg or 7.5mg(there are 10mg too). oxycontin comes in 10,20,40,80,160mg...so depending on the size the price goes up accordingly.
they are the same narcotic, qty determines price
or if you meant roxicodone...thats the same too, but I usually hear about the 30mg one, which would explain the 3x the price you mentioned
