Previous studies on tapentadol have included multi\u2010morbid patients in whom confounders exclude detailed assessment of the mechanistic effects and strict comparison with other opioids or placebo. This study aimed at investigating the effects of tapentadol and oxycodone on gastrointestinal motility and gastrointestinal side effects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>21 healthy males participated in a randomized, double\u2010blind, placebo\u2010controlled, crossover study. Tapentadol (50\u00a0mg twice daily), oxycodone (10\u00a0mg twice daily), or placebo tablets were administered for 14\u00a0days. Segmental gastrointestinal transit times and colonic motility parameters were measured with electromagnetic capsules. Gastrointestinal side effects were assessed using questionnaires.<\/jats:p><\/jats:sec><jats:sec><jats:title>Key Results<\/jats:title><jats:p>During dosing with tapentadol, gastrointestinal side effects and motility parameters were on placebo level. Compared with tapentadol, oxycodone increased whole gut transit time by 17.9 hours (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.015) and rectosigmoid transit time by 6.5 hours (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.005). Compared with tapentadol, oxycodone also reduced long, fast antegrade colonic movements (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.001). In comparison with placebo, oxycodone prolonged whole gut transit time by 31.6 hours, (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.001). Moreover, less long, fast antegrade colonic movements (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.002) were observed during oxycodone. For oxycodone only, slow colonic movements were associated with gastrointestinal side effects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions &amp; Inferences<\/jats:title><jats:p>In this mechanistic study, tapentadol caused significantly less colonic dysmotility and gastrointestinal side effects as compared with oxycodone in equianalgesic doses.<\/jats:p><\/jats:sec>","DOI":"10.1111\/nmo.14131","type":"journal-article","created":{"date-parts":[[2021,5,29]],"date-time":"2021-05-29T18:40:21Z","timestamp":1622313621000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Tapentadol results in less deterioration of gastrointestinal function and symptoms than standard opioid therapy in healthy male volunteers"],"prefix":"10.1111","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4176-7430","authenticated-orcid":false,"given":"Esben Bolvig","family":"Mark","sequence":"first","affiliation":[{"name":"Mech\u2010Sense Department of Gastroenterology and Hepatology Aalborg University Hospital Aalborg Denmark"},{"name":"Mech\u2010Sense Department of Radiology Aalborg University Hospital Aalborg Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3271-1408","authenticated-orcid":false,"given":"Rasmus Bach","family":"Nedergaard","sequence":"additional","affiliation":[{"name":"Mech\u2010Sense Department of Gastroenterology and Hepatology Aalborg University Hospital Aalborg Denmark"},{"name":"Department of Clinical Medicine Aalborg University Aalborg Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6160-5519","authenticated-orcid":false,"given":"Tine Maria","family":"Hansen","sequence":"additional","affiliation":[{"name":"Mech\u2010Sense Department of Radiology Aalborg University Hospital Aalborg Denmark"},{"name":"Department of Clinical Medicine Aalborg University Aalborg Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7816-6762","authenticated-orcid":false,"given":"Thomas Dahl","family":"Nissen","sequence":"additional","affiliation":[{"name":"Mech\u2010Sense Department of Gastroenterology and Hepatology Aalborg University Hospital Aalborg Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8722-0070","authenticated-orcid":false,"given":"Jens Br\u00f8ndum","family":"Fr\u00f8kj\u00e6r","sequence":"additional","affiliation":[{"name":"Mech\u2010Sense Department of Radiology Aalborg University Hospital Aalborg Denmark"},{"name":"Department of Clinical Medicine Aalborg University Aalborg Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7997-1533","authenticated-orcid":false,"given":"S.
