Meptazinol is an opioid medicine (sometimes called an opiate). It is used to treat moderate-to-severe types of pain. It works by binding to certain tiny areas, called opioid receptors, in your brain and spinal cord (central nervous system). This leads to a decrease in the way you feel pain and your reaction to pain.
