Flow dependent elimination
WebApr 13, 2024 · A boundary layer model was developed to predict the capture of inclusions by steel–slag interface in a turbulent fluid flow, which is based on the detailed analysis of inclusion trajectories. The effective boundary layer for inclusion removal was proposed by a statistical method. It is noticed that the capture of inclusions by steel–slag interface is not … WebB. Flow-Dependent Elimination. In contrast to capacity-limited drug elimination, some drugs are cleared very readily by the organ of elimination, so that at any clinically realistic concentration of the drug, …

WebAbstract. The effect of blood flow rates on hepatic elimination of metoprolol (Met) was studied in a recirculating isolated perfused rat liver system with a constant infusion of Met into the reservoir. This design ensures that, at a steady state, the elimination rate of Met is a constant. The results showed that at flow rates of 10, 20, and 30 ... WebCapacity-dependent Elimination Follows Michaelis-Menten kinetics Rate of elimination V max C m C Saturatable Æ High C leads to V max rate When this happens zero order elimination occurs Three classic drugs: Ethanol Phenytoin Aspirin Flow-dependent Elimination Some drugs metabolized so uickly that blood flow to
