Extrahepatic metabolism
WebOne of the major metabolic pathways of β-estradiol (E2) is glucuronidation at the 17-hydroxy position by UGTs. This study was performed to determine E2 17-glucuronidation kinetics in human and rodent liver, small intestine, and kidney microsomes and to clarify the species and tissue differences. WebDec 10, 2014 · The extrahepatic pathways also provided an explanation for the discrepancy between predicted clearance from hepatocyte incubations and the total body clearance of ibrutinib (Shibata and Chiba...

Webextrahepatic tissues than in the liver, making the former less relevant for the clearance of xenobiotics. Local metabolism, however, may lead to tissue-specific adverse responses, … WebIn contrast, CYP1A1 and CYP1B1 are mostly extrahepatic, and are of lesser importance for drug metabolism. CYP1A2 is involved in the metabolism of, e.g., agomelatin, caffeine, clozapine, duloxetine, propranolol, tizanidine, and zolmitriptan, as well as some endogenous compounds, such as melatonin and estradiol.
WebJul 11, 2024 · Extrahepatic drug metabolism takes place in the GI tract, kidneys, lungs, plasma, and skin. Renal excretion completes the process of elimination that begins in the liver. Polar drugs or their metabolites get filtered in the kidneys and typically do not undergo reabsorption. [5] They subsequently get excreted in the urine.
