Non-English and unavailable records, as well as records with non-experimental methodology, were excluded. Inclusion criteria were preclinical studies measuring pain <jats:italic>in vivo<\/jats:italic> upon activation of the K<jats:sub>ATP<\/jats:sub> channel by administering a stimulator or positive modulator.

In total, 126 duplicates were detected. Subsequently, 438 records were screened by title and abstract, resulting in the exclusion of 396. Based on inclusion criteria, 42 studies were included. The main findings of the present systematic review were that K<jats:sub>ATP<\/jats:sub> channel openers can attenuate induced pain in various animal models and potentiate the effects of analgesics.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Local, systemic, spinal, and supraspinal activation of K<jats:sub>ATP<\/jats:sub> channels can attenuate pain and potentiate the efficacy of analgesic drugs. One exception was levcromakalim, as the systemic levcromakalim administration, but not a local application, induced pain. This finding is consistent with those of recent human trials. Future studies should investigate the differences in K<jats:sub>ATP<\/jats:sub> channel activation between rodents and humans, as well as the differences in activation sites between levcromakalim and other K<jats:sub>ATP<\/jats:sub> channel openers.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fphys.2025.1444270","type":"journal-article","created":{"date-parts":[[2025,1,29]],"date-time":"2025-01-29T06:48:17Z","timestamp":1738133297000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Activation of KATP channels in pain modulation: a systematic review of preclinical studies"],"prefix":"10.3389","volume":"16","author":[{"given":"Signe Sch\u00f8nning","family":"Beich","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lili","family":"Kokoti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad Al-Mahdi","family":"Al-Karagholi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,1,29]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"438","DOI":"10.3390\/ph16030438","article-title":"Involvement of potassium channel signalling in migraine pathophysiology","volume":"16","author":"Al-Karagholi","year":"2023","journal-title":"Pharm.
