Abstract
Background: Opioid Use Disorder (OUD) is an escalating public health problem with over 100,000 drug overdose-related deaths last year most of them related to opioid overdose, yet treatment options remain limited. Non-invasive Vagal Nerve Stimulation (nVNS) can be delivered via the ear or the neck and is a non-medi- cation alternative to treatment of opioid withdrawal and OUD with potentially widespread applications.
Methods: This paper reviews the neurobiology of opioid with- drawal and OUD and the emerging literature of nVNS for the ap- plication of OUD. Literature databases for Pubmed, Psychinfo, and Medline were queried for these topics for 1982-present.
Results: Opioid withdrawal in the context of OUD is associated with activation of peripheral sympathetic and inflammatory sys- tems as well as alterations in central brain regions including ante- rior cingulate, basal ganglia, and amygdala. NVNS has the potential to reduce sympathetic and inflammatory activation and counter the effects of opioid withdrawal in initial pilot studies. Preliminary studies show that it is potentially effective at acting through sym- pathetic pathways to reduce the effects of opioid withdrawal, in addition to reducing pain and distress.
Conclusions: NVNS shows promise as a non-medication ap- proach to OUD, both in terms of its known effect on neurobiology as well as pilot data showing a reduction in withdrawal symptoms as well as physiological manifestations of opioid withdrawal.
