TabletsClinical Overview
Tapentadol Tablets (50mg immediate-release, 100mg extended-release) is a centrally acting synthetic analgesic with a dual mechanism: potent mu-opioid receptor agonism (MOR) and noradrenaline reuptake inhibition (NRI). Unlike tramadol, it has minimal serotonergic activity (virtually eliminating serotonin syndrome risk) and does not rely on metabolic CYP2D6 bioactivation for efficacy, producing consistent and predictable analgesia. Indicated for management of severe acute pain (immediate-release) and severe chronic pain / painful diabetic peripheral neuropathy (extended-release).
