Mechanism of Action
Tramadol is a centrally acting opioid analgesic which binds to mu-opioid receptors and weakly inhibits the reuptake of norepinephrine and serotonin. Paracetamol, a para-aminophenol derivative, has analgesic, antipyretic and weak anti-inflammatory activity. Together, tramadol and paracetamol has faster onset of action compared to tramadol alone and longer duration of action compared to paracetamol alone.
