The entire class of medications called opioids are the strongest pain medications. These include morphine, hydromorphone, Meperidine, Oxycodone, Hydromorphone, Codeine, methadone and fentanyl. Of these medications, fentanyl is the most potent. However, the overall pain relief that can be achieved with the opioids is dose-dependent, and so in a lot of cases one can work just as well as another.
