Background:
Gabapentin and pregabalin were developed for epilepsy and neuropathic pain. They work via voltage-gated calcium channels and are used for broad-spectrum diagnoses, e.g., epilepsy, neuropathic pain, other chronic pain syndromes, anxiety disorders, alcohol-drug withdrawal syndromes, agitation, insomnia, etc. Especially in a world dealing with the opioid crisis, gabapentinoids were considered safer alternatives to opioid analgesics.
Methods:
This review aims to comprehensively search and summarize recent studies concerning the abuse of gabapentinoids published between 2021 and 2022 from various regions around the world.
Results:
Studies have highlighted that a history of substance use disorder is a significant risk factor for gabapentinoid abuse. Concurrent abuse of gabapentinoids with illicit drugs can exacerbate drug-related damages. Drug screening and postmortem toxicology tests have revealed an increase in gabapentinoid consumption. In response to the abuse potential, several countries have classified gabapentinoids as controlled substances.
Conclusion:
Gabapentinoids are highly abused molecules worldwide. Physicians should be aware of their abuse potential.
