A new vaccine hindered the often-abused prescription opioids oxycodone and hydrocodone from entering the brain and suppressed one of the drugs’ signature central nervous system effects. The findings warrant continued development of the vaccine as a potential aid in the treatment of oxycodone and hydrocodone abuse and dependence.
People who use prescription opiates nonmedically are more likely to consider suicide than those who use these medications only appropriately or not at all. A recent NIDA-supported study also disclosed that the risk for suicidal thoughts remains elevated after cessation of use.
NIDA Program Officer Dr. David Thomas speaks about the intertwined problems of pain and prescription opioid abuse, as well as the research supported by NIDA and the National Institutes of Health to address these problems.
Researchers report a significant advance in the search for medications that can suppress pain but avoid opioids’ abuse potential and other undesirable CNS effects. A new compound reduces mouse responses in animal models of neurogenic and chronic inflammatory (e.g., arthritic) pain. The compound, called UB937, enhances the natural pain-killing activity of the neurotransmitter anandamide, and exerts its analgesic effects entirely in peripheral tissues, without entering the brain.
