WebJan 1, 2014 · High clearance, flow-dependent elimination: For some drugs (e.g., lidocaine, morphine, nitroglycerin, propranolol, and verapamil), the extraction ratio is high (E >0.7), and the drug is removed by the liver almost as rapidly as the organ is perfused by the blood containing the drug. Consequently, the hepatic clearance of these drugs approaches ... WebFlow dependent elimination. The drugs are cleared so well most of the drug is eliminated on first pass through the organ.

WebElimination is approximately biphasic, with mean half-times of 30 minutes and 6.6 hours (Giussani 2008). The whole-body elimination rate in rats is dose-dependent (Bibr and Lener 1973). Following oral administration of Mo [VI] at doses <3 μg molybdenum/kg, elimination was mono-phasic with a half-time of approximately 47 hours. Following … WebIn that case, clearance is not blood-flow-dependent but depends on enzymatic activity and blood binding. Binding to blood will limit the elimination.
