sufentanil + dexketoprofen tromethamine

This is a combination drug consisting of sufentanil, a potent synthetic opioid analgesic, and dexketoprofen tromethamine (also known as dexketoprofen trometamol), a non-steroidal anti-inflammatory drug (NSAID). Sufentanil acts primarily as an agonist at the mu-opioid receptor, providing strong analgesia and sedation. It is used for induction and maintenance of anesthesia, management of severe acute pain, and in some settings for labor analgesia[3]. Dexketoprofen tromethamine is the S(+)-enantiomer of ketoprofen formulated as a water-soluble salt; it inhibits both COX-1 and COX-2 enzymes to reduce prostaglandin synthesis, resulting in analgesic, anti-inflammatory, and antipyretic effects[4][6][8]. The combination aims to provide synergistic or supra-additive pain relief by targeting different mechanisms—central opioid pathways (sufentanil) and peripheral/central prostaglandin-mediated pathways (dexketoprofen)[1][2]. This multimodal approach may allow lower doses of each component with improved efficacy and potentially fewer side effects compared to higher doses of either agent alone.
