Comparison of urinary excretion characteristics of ethanol and ethyl glucuronide.
This study compared the urinary excretion characteristics of ethyl glucuronide (EtG) with that of ethanol, with focus on the effect of water-induced diuresis. Six healthy volunteers ingested an ethanol dose of 0.5 g/kg (range 25.0-41.5 g) as 5% (v/v) beer in 30 min and the same volume of water after 3 h. Urine collections were made before starting the experiment and at timed intervals over 31.5...
متن کاملUrinary excretion of buprenorphine, norbuprenorphine, buprenorphine-glucuronide, and norbuprenorphine-glucuronide in pregnant women receiving buprenorphine maintenance treatment.
BACKGROUND Buprenorphine (BUP) is under investigation as a medication therapy for opioid-dependent pregnant women. We investigated BUP and metabolite disposition in urine from women maintained on BUP during the second and third trimesters of pregnancy and postpartum. METHODS We measured BUP, norbuprenorphine (NBUP), buprenorphine glucuronide (BUP-Gluc), and NBUP-Gluc concentrations in 515 uri...
متن کاملBiliary excretion of glycyrrhetinic acid: glucuronide-conjugate determination following a pharmacokinetic study of rat bile.
Liquorice is a commonly prescribed herb in traditional Chinese medicine with the primary constituent, glycyrrhetinic acid (GA) responsible for the toxic effects arising from its chronic consumption. Hepatic transformation and biliary excretion of GA are significant and well-documented pharmacokinetic pathways in humans, while glucuronide conjugates are the major identified metabolites. Here we ...
متن کاملMechanisms of impaired biliary excretion of acetaminophen glucuronide after acute phenobarbital treatment or phenobarbital pretreatment.
Previous studies have demonstrated that phenobarbital (PB) significantly impairs the biliary excretion of acetaminophen glucuronide (AG) in rats. Studies also suggested that Mrp2 mediates AG biliary excretion, and Mrp3 is involved in AG basolateral export. It was hypothesized that inhibition of Mrp2-mediated AG transport by PB or PB metabolites, and PB induction of Mrp3, may contribute to the i...
متن کاملStereoselective metabolism of benoxaprofen in rats. Biliary excretion of benoxaprofen taurine conjugate and glucuronide.
Benoxaprofen (BOP) was administered iv to bile duct-cannulated rats at a dose of 10 mg/kg. BOP and its metabolites in plasma, urine, and bile were quantified using HPLC. A previously unidentified BOP metabolite was found in HPLC chromatograms of rat bile, and the metabolite was isolated chromatographically. Positive-ion fast-atom bombardment (FAB) MS analysis of the compound showed [M+H]+ at m/...
