HTX-011 is an extended-release, dual-acting local anesthetic consisting of bupivacaine (sodium-channel blocker) and low-dose meloxicam (non-steroidal anti-inflammatory drug [NSAID]) applied needle-free during surgery. Introducing low-dose meloxicam addresses the limited efficacy of liposomal bupivacaine in acidic inflamed tissues and allows enhanced analgesic effects over three days. It has great promise to be an extremely effective postoperative pain regimen and produce an opioid-free surgical recovery, as it has consistently significantly reduced pain scores and opioid consumption through 72 h. This manuscript provides an updated, concise narrative review of the pharmacology, clinical efficacy, safety and tolerability of this drug and its applications to prevent postoperative pain.

Lay abstract HTX-011 is a local anesthetic (a drug to induce temporary loss of sensation or awareness, usually during a medical procedure), which is made up of a combination of two drugs and applied needle-free during surgery. It has great promise to provide effective treatment for postoperative pain (pain after an operation), allowing patients to have an opioid-free option for their pain relief. This paper reviews how this drug works and the clinical trials that have taken place so far to investigate its safety and effectiveness in reducing pain after an operation.
