(1) Pharmacokinetic: Oral bioavailability (72% with a high inter-individual variability) was reported in 47 stable patients in a paediatric intensive care unit. (2) Analgesia: In a double-blind randomized controlled trial of 45 children, no difference in analgesia was found between oral and intravenous administration after cleft palate repair. (3) Fever: In an open-label prospective observational study of 200 children, temperature decreased faster after intravenous than oral administration but was similar 4 hours later.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Available data are insufficient to guide clinicians with a rational choice of route of administration. Oral bioavailability should be studied in paediatric populations outside the intensive care unit. Despite the widespread use of intravenous acetaminophen, there is little evidence to suggest that it improves analgesia compared to the oral formulation. Similarly, fever weans faster but whether this translates into any meaningful clinical outcome is unknown. The lack of data plus the significantly higher costs of intravenous acetaminophen should motivate further research.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/pch\/pxaa137","type":"journal-article","created":{"date-parts":[[2021,3,13]],"date-time":"2021-03-13T08:29:33Z","timestamp":1615624173000},"page":"337-343","source":"Crossref","is-referenced-by-count":4,"title":["Newly approved IV acetaminophen in Canada: Switching from oral to IV acetaminophen.
