Tramadol is a primary component that belongs to the mu-agonist opioid painkiller drugs that act on the central nervous system. This analgesic releases endorphins that alter the pain signals the nerve cells send to the brain, thus inducing a feeling of euphoria (feeling of happiness). It acts on the pain receptors that stop the pain sensation to the rest of the body. Tramadol is also a serotonin-norepinephrine reuptake inhibitor that treats depression or anxiety caused by pain.
