NuMorphan has been around for a very long time. But now Endo is making an extended release version like NuMorphanContin (heh, probably it sounds more poetic than that, whatever name they pick). Now an already powerful drug will be available in a much higher strength. A lot of companies are doing this, selling XR versions of a drug that has lost its patent protection (Xanax XR, for example).
