Web10 mrt. 2024 · Methacetin, a derivative of phenacetin, goes through the hepatic oxidase system in the liver mitochondria, where it is metabolized to acetaminophen and carbon dioxide [10]. Previous studies have shown that methacetin can reliably differentiate between healthy controls and patients with cirrhosis [11–15]. Some studies have also …
Web11 jan. 2005 · Methacetin has numerous advantages as substrate for 13 C breath tests in liver function testing: Aminopyrine is the best investigated hepatic 13 C‐labelled substrate so far, but it has a slow clearance rate and its use bears the risk of serious side‐effects, such as agranulocytosis. 25 Methacetin is quickly metabolized than aminopyrine, but innocuous.
