Promising new compound offers an alternative to cannabis for pain relief
Researchers may have discovered a groundbreaking solution for pain management that avoids addiction and side effects.
Currently, opioids play a significant role in pain treatment worldwide; however, their prolonged use poses serious risks of addiction and adverse effects. As medical cannabis gains traction, some researchers are seeking a safer, non-psychoactive alternative. A team from Washington University in St. Louis and Stanford University has potentially found a breakthrough. Their findings, published on March 5 in Nature, reveal an innovative pain relief treatment that is non-addictive and does not alter mental states.
A cannabis alternative that does not enter the brain
Medical cannabis operates through cannabinoids, which bind to receptors in the body, particularly in the brain and nerve cells associated with pain. By attaching to these receptors, cannabinoids can modify pain perception. However, this effect may come with mood changes, dependency, and other undesirable side effects.
The researchers developed a compound that mimics the effects of natural cannabinoids but with a crucial distinction: it does not cross the blood-brain barrier, which isolates the brain from the rest of the body. “The compound we created binds to pain-reducing receptors in the body but cannot reach the brain. This means it avoids psychoactive side effects like mood changes and does not create dependency since it does not act on the brain's reward center,” explains lead author Professor Susruta Majumdar.
Encouraging results in mice
During testing, mice were injected twice daily with the compound for nine days. The result was a significant reduction in pain for mice suffering from nerve injuries and migraines, all without developing dependence.
The researchers plan to continue developing this compound into an oral medication. Their goal is to initiate clinical trials to evaluate its effectiveness in humans. If successful, this medication could provide a revolutionary alternative to current pain management treatments, especially for chronic pain management.
