Tapentadol is a centrally-acting pain reliever that inhibits pain signals by binding to mu-opiate receptors in the brain and in the spinal cord. It is also said to inhibit norepinephrine reuptake to alter pain response.

Tapentadol is used in the treatment of moderate to severe acute pain, and in neuropathic pain associated with diabetic neuropathy.
