More than half of heroin-addicted patients treated with naltrexone via an implanted delivery device maintained abstinence throughout a 6-month clinical trial in Saint Petersburg, Russia. The implant device, which releases a steady dose of naltrexone continuously for 2 months, averted relapse to heroin use three times as effectively as daily oral doses of the medication.
Reports on research showing that the neurons that deliver dopamine to two regions of the brain's mesolimbic reward system respond differently to opioids, an important finding for drug treatment research.
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.
A significant portion of individuals who are addicted to opioid painkillers may initiate and maintain abstinence with a brief but intensive outpatient detoxification treatment followed by opioid antagonist therapy using naltrexone.
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.
