Technical Description & Application Profile
Bupivacaine is a highly potent, long-acting amide-type local anesthetic. Due to its superior receptor binding affinity, it provides a significantly extended duration of analgesia compared to Lidocaine or Mepivacaine.
As a raw material supplier, Shaanxi Sunrise Pharmaceutical provides this API exclusively for downstream pharmaceutical manufacturers. Our meticulously synthesized Bupivacaine powder features a highly stable crystalline structure, excellent thermal stability, and a consistent particle size distribution. It serves as the critical active pharmaceutical ingredient (API) for compounding facilities and manufacturers producing epidural, spinal, and peripheral nerve block formulations.
