Additional Information

Tapentadol (trade name Nucynta, Palexia, In India - ZYNTAP)  is a centrally acting analgesic with a dual mode of action as an agonist at the μ-opioid receptor and as a norepinephrine reuptake inhibitor. While its analgesic actions have been compared to tramadol and oxycodone, its general potency is somewhere between tramadol and morphine in effectiveness. Tapentadol is a new molecular entity that is structurally similar to Tramadol (Tramal). It has opioid and nonopioid acitivity in a single compound. In the US, Tapentadol is FDA approved for the treatment of moderate to severe acute pain. Due to the dual mechanism of action as an opioid agonist and norepinephrine reuptake inhibitor, there is potential for off label use in chronic pain.
