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.
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.
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.
Treatment with an extended-release stimulant medication plus cognitive behavioral therapy was associated with reductions in cocaine use and in attention-deficit/hyperactivity disorder symptoms in patients with both disorders.
