How to deal with patients addicted to pain-relieving opioids
Fred Nyberg
Uppsala University, Sweden
Over the past decade, the prescribing of opioids has increased dramatically in Western countries and in particular in North
America. In parallel with this increase in opioid addiction, overdose, and associated deaths have been seen. A similar
situation occurs in Sweden, where an about 40% increase in drug-related deaths has been documented, over the past decade,
mainly due to opioids. These include synthetic drugs as methadone, buprenorphine and fentanyl and an increase has been seen
in both males and females. A certain part of the increase is seen in opioid deaths combined with benzodiazepines. Although
opioid addiction is effectively treated via a multidisciplinary approach including agonist opioid treatment and psychosocial
intervention there are some difficulties. Misuse and diversion of pain medicines, like methadone and buprenorphine comprise
a significant problem in Sweden as well as in other Nordic countries as these problems are linked to poor treatment compliance
and increases in risk of blood-borne infections, crime, and mortality. To address this problem, changes in medicines used in
some Nordic have already been implemented and considerations are under way in others. The new guidelines for treatment of
opioid addicts in Sweden recommend combination of buprenorphine-naloxone before mono-buprenorphine. However, even
if the occurrence of misuse and diversion of opioid medicine can be reduced there are other issues not always considered. Many
opioid addicts in Sweden are infected by Hepatitis C Virus (HCV) and many of these have not been diagnosed and although
we have effective medicines against HCV a great part are in lack of treatment. Another issue is that long-term opioid treatment
may result in effects on the brain leading to cognitive decline. This presentation will deal with all these problems and in
particular it will focus on the possibility to reverse opioid-induced damages on brain areas associated with cognitive function.
