It functions by attaching itself to the central nervous system's mu-opioid receptors, which blocks pain signals. For the treatment of moderate to severe pain, such as post-operative pain or chronic pain disorders, tapentadol is typically administered. Tapentadol functions by two different mechanisms. Like classic opioids like morphine, it functions as a mu-opioid receptor agonist as well as a norepinephrine reuptake inhibitor. In comparison to some other opioids, this dual action is expected to relieve pain with a possible decreased risk of side effects.
