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.
Legally protected marijuana dispensaries (LMDs) were associated with lower rates of dependence on prescription opioids, and deaths due to opioid overdose, than would have been expected based on prior trends. However, LMDs also were associated with higher rates of recreational marijuana use and increased potency of illegal marijuana.
Treatment that combines use of Bp/Nx and memantine may enable young adults addicted to opioids establish lasting abstinence after a relatively brief course of medication-assisted therapy, a pilot trial suggests.
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.
Two recent studies suggest that genotyping may enable clinicians to base therapies on individual patients’ potential responsiveness to opioid drugs’ therapeutic effects and vulnerability to their harmful effects.
Intensified screening for HIV among injection drug users receiving opioid agonist therapy could prevent more than twice as many new infections as current screening practice. A recent study based on mathematical modeling found that screening every 6 months instead of annually, and adding viral RNA testing to the currently used HIV antibody testing, could improve both effectiveness and cost-effectiveness.
