At a glance
| Generic name | Butorphanol and dexmedetomindine |
|---|---|
| Sponsor | The Affiliated Hospital of Qingdao University |
| Drug class | Opioid agonist-antagonist combined with alpha-2 adrenergic agonist |
| Target | Opioid receptors (kappa, sigma, mu) and alpha-2 adrenergic receptors |
| Modality | Small molecule |
| Therapeutic area | Anesthesia and Perioperative Medicine |
| Phase | FDA-approved |
Mechanism of action
Butorphanol binds to opioid receptors (primarily kappa and sigma agonist, mu antagonist/partial agonist) to provide pain relief. Dexmedetomidine selectively binds alpha-2 adrenergic receptors in the central nervous system to produce sedation, anxiolysis, and analgesia. The combination is used for perioperative sedation and analgesia, with complementary mechanisms reducing the required dose of each agent.
