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.
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.
Men benefit more than women from nicotine replacement therapy for smoking cessation because nicotine affects a key neuroreceptor differently in the two sexes, a NIDA-sponsored study suggests. The findings highlight the need for alternative therapies for women smokers, and point to the female hormone progesterone as a potential therapeutic target.
