Previously, doses of 5 to 10 mg of morphine have been shown to delay gastric emptying time. However, the effect of lower doses of morphine on gastric emptying in humans has not been reported. In this study, the effects of intravenous morphine 0.05 mg\/kg\u20143.5 mg for 70\u2010kg body weight, a dose that can cause analgesia\u2014on gastric emptying were evaluated in a double\u2010blind, randomized, placebo\u2010controlled study in 15 healthy human volunteers using the acetaminophen test. Our data indicated that this low dose of morphine significantly prolonged the gastric emptying time. Thus, even small doses of morphine inhibit gastric emptying. This effect may be important in patients undergoing surgery, in patients receiving other oral medications after surgery in ambulatory settings, and in instances of patient\u2010controlled analgesia.<\/jats:p>","DOI":"10.1177\/009127009803801105","type":"journal-article","created":{"date-parts":[[2007,6,21]],"date-time":"2007-06-21T20:52:18Z","timestamp":1182459138000},"page":"1017-1020","source":"Crossref","is-referenced-by-count":69,"title":["Effects of Low\u2010Dose Morphine on Gastric Emptying in Healthy Volunteers"],"prefix":"10.1002","volume":"38","author":[{"given":"Chun\u2010Su","family":"Yuan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph F.","family":"Foss","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"O'Connor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael F.","family":"Roizen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan","family":"Moss","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,3,8]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/55.12.1189"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2044.1994.tb03376.x"},{"key":"e_1_2_1_4_2","first-page":"16","volume-title":"Absorption and Distribution of Drugs.","author":"Brodie BB","year":"1964"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-199710000-00003"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5381.1973.tb08339.x"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/cpt1978244420"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1445-2197.1985.tb00885.x"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-199710000-00008"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5381.1959.tb00924.x"},{"key":"e_1_2_1_11_2","first-page":"65","volume-title":"Synthetic Antidiarrheal Drugs: Synthesis\u2010preclinical and Clinical Pharmacology.","author":"Niemegeers C","year":"1976"},{"key":"e_1_2_1_12_2","doi-asserted-by":"crossref","first-page":"1575","DOI":"10.1093\/clinchem\/27.9.1575","article-title":"Fluorescence polarization immunoassay.
