WebFentanyl is metabolized and eliminated almost exclusively by the liver; thus, it has been assumed that its pharmacokinetics would be minimally altered by kidney failure. 112 However, despite limited pharmacokinetic data, hepatic clearance and extraction of drugs with high hepatic extraction ratios (eg, fentanyl) could potentially be inhibited by uremia … http://envismadrasuniv.org/Physiology/pdf/Bilirubin%20metabolism%20Applied%20physiology.pdf
WebBilirubin glucuronides are actively transported into the bile canaliculi by the ATP-utilizing pump MRP2. Bilirubin is degraded in the intestine by bacteria into urobilinogens, which are partly excreted in the urine. Increased production, reduced uptake and low glucuronida-tion capacity can increase plasma unconjugated bilirubin levels.
