HTX-011 effectively reduces postoperative pain intensity and opioid use in the elderly.

HTX-011 (ZYNRELEF™) is an extended-release, dual-acting local anesthetic containing bupivacaine and meloxicam. In bunionectomy and herniorrhaphy studies, HTX-011 resulted in less postoperative pain and less opioid consumption versus bupivacaine HCl. Here we evaluate HTX-011 in patients aged ≥65 years. Patients received placebo, bupivacaine HCl or HTX-011 following surgery. End points included pain intensity, total opioid consumption, opioid-free patients and safety. HTX-011-treated patients reported lower postoperative pain through 72 h versus bupivacaine HCl and placebo. Elderly patients administered HTX-011 used fewer opioids versus bupivacaine HCl, and a greater proportion remained opioid-free through 72 h. HTX-011 was well tolerated with a safety profile similar to bupivacaine HCl and placebo. HTX-011 maintained effectiveness and was well tolerated in elderly patients. Clinical Trial registration numbers: NCT03295721 and NCT03237481.
