The available dosages for Oxycontin (oxycodone, extended release) are: 10mg, 15mg, 20mg, 30mg, 40mg, 60mg, and 80mg. Purdue introduced the 15, 30, and 60mg in 2008. They used to manufacture a 160mg tablet, but I believe it has been discontinued. The available dosages for Percocet (oxycodone + acetaminophen, instant release are: 2.5/325, 5/325, 5/500 (capsule), 7.5/325, 7.5/500, 10/325, and 10/650. Hope that helps.
