April 2012 Women with post-traumatic stress disorder (PTSD) who abused drugs responded better to substance abuse treatment after their PTSD symptoms improved, according to a recent study, which also found that reductions in substance abuse did not ease PTSD severity
July 2012 Sublingual buprenorphine is a safe and effective alternative to methadone for treating opioid dependence during pregnancy, finds the Maternal Opioid Treatment: Human Experimental Research (MOTHER) study, a NIDA-supported clinical trial. Women who received either medication had similar pregnancy and birth outcomes, but infants born to women who received buprenorphine had milder symptoms of neonatal opioid withdrawal.
July 2012 Soluble-film preparations of buprenorphine suppressed heroin abusers’ withdrawal symptoms with no serious side effects in a recent clinical trial. They dissolved more rapidly in the mouth than the pill form of the medication, providing faster relief.
July 2012 Intensive case management was more effective in increasing treatment engagement and reducing alcohol consumption among depressed participants than among those who were not depressed, according to a followup analysis of a substance abuse treatment study involving women on welfare.
July 2012 Fewer than 12 percent of adolescents who meet diagnostic criteria for prescription opioid abuse or dependence receive any treatment, according to an analysis of data from the 2005 to 2008 National Survey on Drug Use and Health. The most common reason the adolescents gave for not receiving treatment was their lack of perceived need for it.
September 2012 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.
September 2012 New vaccines that aim to promote recovery from cocaine and heroin abuse showed promise in animal testing. Both vaccines induced rats’ immune system to produce high titers of antibodies that inhibit the target drug from reaching the brain. The rats’ behaviors when given access to the target drug indicated that the vaccines reduced the reinforcing effects that, in recovering people, can cause lapses to turn into relapses.
