Several patients have recently presented with a medication history including tapentadol (Nucynta), the newest opioid formulation.  It is approved for treatment of acute moderate-severe pain.  Here are some key points:

  • Mechanism similar to tramadol: mu-receptor agonist, also inhibits norepinephrine reuptake
  • Potency stronger than tramadol, but less then morphine
  • Usual dose is same as tramadol 50-100 mg every 4-6 hours prn pain
  • Schedule II controlled substance, similar to morphine/oxycodone (tramadol is not a controlled substance)
  • Overdose should present like other opioids, but potentially also including tachycardia, serotonergic effects, and seizures (similar to tramadol)
