Choosing an Opioid – Our Best Buy Pick (Consumer Reports)
Unfortunately, the research comparing opioids to each other in the treatment of people who have chronic pain is quite limited. That means that, in terms of effectiveness, one opioid may be better than another – either overall or in treating certain types of pain or certain people – but the medical evidence just does not exist to prove it.
That said, the evidence that does exist suggests strongly that when comparable doses of any of the opioids are used, the relief from pain is about the same. Opioids also seem to produce similar results when quality of life is the main outcome measured.
Thus, there is not enough evidence from the research to say that one opioid is more effective or better than any other in treating people who have chronic pain.
