The purpose of this research was to evaluate a novel long-acting bupivacaine delivery system for control of postoperative pain. Bupivacaine-loaded lipid emulsion (BLE) droplets were created by high-speed homogenization. The BLE droplets were then entrapped into a crosslinked-hyaluronic acid hydrogel system to create an injectable composite gel formulation (HA-BLE). Dynamic light scattering, rheological, and drug release techniques were used to characterize the formulations. A rat sciatic nerve block with a thermal nociceptive assay
