Considerations for perioperative opioid analgesic stewardship in Australia: a focus on tapentadol.

Opioid-related harm remains a serious public health issue in Australia, where there is a strong focus on judicious use of opioids to optimize postoperative patient outcomes. The risks associated with preoperative opioid use (worsened postoperative pain, surgical outcomes, increased length of stay and financial costs) must be balanced with the risks of sub-optimal post-surgical pain management (development of chronic pain, persistent postsurgical opioid use and opioid dependence). In addition to significantly lower rates of gastrointestinal adverse effects (nausea, vomiting, constipation), tapendatol (vs oxycodone) is less likely to cause excessive sedation and opioid-induced ventilatory impairment, may be associated with less withdrawal symptoms of mild to moderate intensity and significantly lower odds of 3-month persistent postoperative opioid use in certain patient populations. Studies included in this review were phase III/meta-analyses, referenced in Australian clinical guidelines and/or published ≤5 years), except for cost-effectiveness analyses, where all known, relevant published analyses were included.
