Research snapshot: Opioid prescriptions common among Medicare beneficiaries

The often devastating misuse of prescription opioids has slowly caught the media and public’s attention in recent years. It is estimated that opioid addiction affected nearly 2.5 million adults in the U.S. in 2014. Some estimates suggest more than 44,000 drug overdose-related deaths occurred in 2013 and nearly one-third of those deaths were attributed to prescription opioids. Furthermore, prescription opioid abuse can often lead to heroin use (and eventual addiction) when addicts can no longer get prescription medication and/or they move on to cheaper, easily accessible and stronger heroin.

Tragically, an estimated 40 people die every day from opioid drug overdoses.

The University of Minnesota is doing its part to take on this public health crisis and recently hosted Pain. Pill. Problem., an all-day conference that examined the many facets of Minnesota’s issues with opiate abuse.

Research snapshot: New tools could help prevent relapse behavior in opioid addiction

Opioid addiction is a crippling problem in society, with an estimated 9 percent of Americans abusing opiates at some point in their life. In Minnesota, opiate overdose deaths have more than tripled since 2000.

Overcoming addiction is extremely challenging, and the risk of relapse persists. A new study from the University of Minnesota Medical School’s Department of Neuroscience identified a potential target for preventing morphine relapse in mice, which brings researchers closer to providing a way for recovering addicts to stay drug-free.
