Summary
Dexborneol enhances pregabalin
Area of Science:
- Pharmacology
- Neuroscience
- Pain Management
Background:
- Pregabalin is a key treatment for neuropathic pain and anxiety.
- Pregabalin monotherapy has limitations including variable efficacy and side effects.
Purpose of the Study:
- To investigate dexborneol's potential to enhance pregabalin's analgesic effects.
- To elucidate the mechanisms underlying this potentiation.
Main Methods:
- Animal models of peripheral nerve injury and incisional pain.
- Integrated approach: behavioral pharmacology, molecular biology, neuromorphology, and lipidomics.
Main Results:
- Dexborneol improved pregabalin's central nervous system delivery and analgesic efficacy.
- Combination therapy reduced HMGB1/ATP release, oxidative stress, neuroinflammation, and glial activation.
- Dexborneol mitigated pregabalin's dose-dependent adverse reactions.
Conclusions:
- Dexborneol acts as an effective adjuvant to pregabalin, improving pain relief and tolerability.
- This combination offers a promising strategy for managing chronic and neuropathic pain.

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

01:15Opioid Analgesics: Synthetic and Semisynthetic Opioids
260
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...
