Potential of N-acetylcysteine in the management of low back pain: a scoping review of studies in humans and animal models
Low back pain (LBP) is a common type of pain that causes disability and impairs cognitive function.

| Summary: | Low back pain (LBP) is a common type of pain that causes disability and impairs cognitive function. With over 80% of adults estimated to experience LBP during their lifetime, this type of pain not only has a significant impact on the individual, but also on public health systems and national economies. Unfortunately, there is no single standard of care for patients with LBP. N-acetylcysteine (NAC), which is used clinically to treat acetaminophen overdose, has recently been tested as a potential treatment for LBP. NAC is inexpensive and commercially available, and it has an established tolerance and safety profile. However, NAC's efficacy in LBP has not been established. This scoping review presents a summary of studies investigating the effects of NAC and the potential benefits in LBP treatment, and highlights its potential molecular mechanisms and side effects. A systematic literature search in Pubmed/MEDLINE, Embase, Scopus, Science Direct, Web of Science, Cinahl, and Lilacs databases was conducted. The PRISMA-ScR checklist was used to ensure integrity of the review. The scoping review protocol was registered in the Open Science Framework. No limit was set on study language and publication date. In total, 2357 articles were located, of which 16 were included. The studies show that NAC has potential for LBP treatment, but data are derived only from a few clinical trials and preclinical studies. Thus, there is much to learn and more clinical studies should be performed before NAC can be clinically recommended for the treatment of LBP. |
