Opioids, NSAIDs, acetaminophen, gabapentinoids, muscle relaxants, anticonvulsants, and antidepressants are the most used medications for chronic pain and carry significant side effects, including gastric bleeding, hepatotoxicity, stroke, kidney damage, constipation, dizziness, and arrhythmias. Opioids in particular carry the risk of long-term dependence, drug tolerance, and overdose. In 2022, 81,806 people died from opioid overdose in the United States alone. Alternative treatments for chronic pain are critically needed, and nanotechnology has emerged as a promising means of achieving effective long-term analgesia while avoiding the adverse side effects associated with conventional pharmacological agents. Nanotechnology-based treatments include liposomes, Poly Lactic-co-Glycolic Acid (PLGA) and other polymeric nanoparticles, and carbon-based polymers, which can help mitigate those adverse side effects. These nanomaterials can serve as drug delivery systems that facilitate controlled release and drug stability via the encapsulation of free molecules and protein-based drugs, leading to longer-lasting analgesia and minimizing side effects. In this review, we examine the role of nanotechnology in addressing concerns associated with conventional chronic pain treatments and discuss the ongoing efforts to develop novel, nanotechnology-based treatments for chronic pain such as nanocapacitor patches, gene therapy, the use of both viral and non-viral vectors, CRISPR, and scavengers.<\/jats:p>","DOI":"10.3390\/pharmaceutics16111479","type":"journal-article","created":{"date-parts":[[2024,11,20]],"date-time":"2024-11-20T07:02:58Z","timestamp":1732086178000},"page":"1479","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Nanotechnology in Pain Management"],"prefix":"10.3390","volume":"16","author":[{"given":"Andrew","family":"Torpey","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, Stony Brook University Hospital, Stony Brook, NY 11794, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily","family":"Bellow","sequence":"additional","affiliation":[{"name":"Renaissance School of Medicine, Stony Brook University, Stony Brook, NY 11794, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronica","family":"Samojedny","sequence":"additional","affiliation":[{"name":"Renaissance School of Medicine, Stony Brook University, Stony Brook, NY 11794, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sukhpreet","family":"Ahluwalia","sequence":"additional","affiliation":[{"name":"Department of Surgery, Stony Brook University Hospital, Stony Brook, NY 11794, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amruta","family":"Desai","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Stony Brook University Hospital, Stony Brook, NY 11794, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William","family":"Caldwell","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Stony Brook University Hospital, Stony Brook, NY 11794, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5641-5908","authenticated-orcid":false,"given":"Sergio","family":"Bergese","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Stony Brook University Hospital, Stony Brook, NY 11794, USA"},{"name":"Department of Neurosurgery, Stony Brook University Hospital, Stony Brook, NY 11794, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"328","DOI":"10.1097\/j.pain.0000000000002291","article-title":"Prevalence of chronic pain among adults in the United States","volume":"163","author":"Yong","year":"2022","journal-title":"Pain"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2313563","DOI":"10.1001\/jamanetworkopen.2023.13563","article-title":"Estimated Rates of Incident and Persistent Chronic Pain Among US Adults 2019-2020","volume":"6","author":"Nahin","year":"2023","journal-title":"JAMA Netw.
