Experimental drug could offer pain relief without the side effects of opioids

  • Researchers at Duke University developed an experimental drug called SBI-810 to relieve pain without opioid side effects.
  • The drug responds to urgent needs as overdose deaths, mostly from opioids, have increased since the 1990s despite a recent decline.
  • SBI-810 targets neurotensin receptor 1 using biased agonism, activating pain relief without causing addiction or common opioid side effects like constipation.
  • In mice, SBI-810 outperformed drugs like gabapentin and oliceridine by reducing pain from surgery, fractures, and nerve injury without sedation or memory problems.
  • Still in early development, SBI-810 could offer a safer option for acute and chronic pain, potentially aiding those recovering from surgery or with diabetic nerve pain.
