Overview

HYR-PB21 is a liposomal formulation of bupivacaine, a long-acting amide-type local anesthetic. Developed by Jiangsu Hengrui Pharmaceuticals, it is designed for local infiltration to provide extended-duration postoperative analgesia. The formulation utilizes a multivesicular liposome (MVL) delivery system that allows for the sustained release of bupivacaine over a period of up to 72 hours. This prolonged release profile is intended to provide continuous pain relief at the surgical site, potentially reducing the requirement for systemic opioids and improving patient recovery outcomes. HYR-PB21 is currently being evaluated in Phase III clinical trials in China for the management of postoperative pain following procedures such as hemorrhoidectomy.
