                  Opioid analgesics are essential for the treatment of moderate to severe
                  cancer pain. Constipation, nausea, vomiting, drowsiness and pruritus
                  are common AEs of opioids.

                  Tramadol acts  both as a  central opiate agonist and central nervous
                  system reuptake inhibitor  of norepinephrine  and serotonin. Liver or
                  renal impairment may require dose adjustments because of tramadol

                  reported  with the use of tramadol especially  with concurrent  use of
                  other serotonergic drugs e.g. antidepressants. 29, level III

                  The use of tramadol is prevalent in cancer pain management although

                  compared with morphine based on very low-quality evidence. Tramadol
                  doses ranged from 50 - 600 mg/day with the most common dose being
                  300 - 400 mg/day in line with the usual clinical practice. Comparisons

                  2016 comparing weak opioids with low-dose morphine with the latter
                  having a higher percentage of patients achieving a reduction in pain
