There are a large variety of analgesics or painkillers that it is almost impossible to name all of them. Also, pharmaceutical companies are always inventing and creating new ones. These analgesics can be categorized based on their ingredients and purposes. These categories include analgesic combinations, antimigraine agents, CGRP inhibitors, cox-2 inhibitors, miscellaneous analgesics, narcotic analgesic combinations, narcotic analgesics, nonsteroidal anti-inflammatory drugs, and salicylates.
However, the most commonly used analgesic drugs include oxycodone, morphine, tramadol, codeine, Darvocet, propoxyphene, marijuana and salicylic acid. Using these analgesic drugs when you are in pain is a good thing because it can stop the pain, but you can also get addicted to them. Besides having to endure the side effects, you may get addicted to them and need help to stop taking them.
