bupivacaine + ibuprofen

Bupivacaine + ibuprofen is a combination of two drugs used for multimodal analgesia, particularly in the perioperative and postoperative setting. Bupivacaine is an amide-type local anesthetic that works by blocking voltage-gated sodium channels on neuronal membranes, thereby inhibiting nerve impulse transmission and providing local or regional anesthesia. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing the synthesis of prostaglandins involved in pain, inflammation, and fever. The combination aims to provide synergistic pain relief by targeting different mechanisms—local nerve blockade from bupivacaine and systemic anti-inflammatory effects from ibuprofen—thereby reducing opioid requirements after surgery[1][3][7].
