Dr. Thomas Kosten of Baylor College of Medicine and Dr. Peter Burkhard of the University of Connecticut are the recipients of NIDA’s 2011 Avant-Garde Awards for Innovative Medication Development Research. Dr. Kosten is developing a vaccine against methamphetamine abuse and Dr. Burkhard is developing a vaccine to counter nicotine addiction.
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.
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.
New studies show that two novel compounds powerfully suppressed animals’ pain responses, while producing little or none of the respiratory depression and liability for misuse and abuse associated with morphine and other typical opioids.
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.
Patients who don’t take their medications as prescribed often put themselves at risk for problems including misdiagnoses, complications, and death. A study suggests that adding low doses of quinine to patients’ medications could provide an inexpensive, reliable, and safe method of monitoring whether patients are taking their medications as directed.
Ketoprofen, an anti-inflammatory agent commonly prescribed to treat arthritis, reduces neuronal damage in rats that have been exposed to chronic stress and methamphetamine. If this finding of a recent NIDA-supported study extrapolates to humans, anti-inflammatory medications may gain a place in the treatment of methamphetamine addiction.
