Clinical Trials

Multiple clinical trials evaluate bupivacaine hydrochloride across indications including postoperative pain, video-assisted thoracic surgery, mastectomies, lumbar spine surgery, and hip fractures managed with spinal anesthesia. Spanning Phase II through Phase IV as well as non-interventional evaluations, these predominantly not-yet-recruiting studies are sponsored by academic institutions—including the University of Utah, Naval Medical Center Portsmouth, and The University of Hong Kong—alongside industry partners like Pacira Pharmaceuticals Inc. Research protocols focus on local and regional anesthetic efficacy, examining techniques such as erector spinae plane peripheral catheter infusions and adductor canal blocks.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Bupivacaine HCl selectively binds to the intracellular domain of voltage-gated sodium channels, blocking transmembrane sodium influx and inhibiting intracellular cAMP production to impair nerve impulse propagation. This targeted blockade prevents depolarization in peripheral sensory neurons, providing sustained local anesthesia and analgesia essential for managing postoperative pain in patients undergoing video-assisted thoracic, oncological, and orthopaedic surgeries.

Appendix RUO and cGMP Quality Standards
