Nonlinear kinetics is usually due to saturation occuring in one of the pharmacokinetic mechanisms: protein binding, hepatic metabolism, or active renal transport of the drug. Saturable elimination: above a certain drug concentration, the elimination rate tends to reach a maximal value. Once this maximum capacity is reached, …

WebAug 28, 2024 · As a meaningful measure of pharmacokinetics, half-life applies to drugs with first-order kinetics. First-order kinetics means that the elimination of the drug directly depends on the initial dose of the drug. With a higher initial dose, more drug is cleared. Most drugs follow first-order kinetics.

In pharmacology, clearance is a pharmacokinetic measurement of the volume of plasma from which a substance is completely removed per unit time. Usually, clearance is measured in L/h or mL/min. The quantity reflects the rate of drug elimination divided by plasma concentration. Excretion, on the … See more The clearance of a substance is the volume of plasma that contains the same amount of the substance as has been removed from the plasma per unit time. When referring to the function of the kidney, clearance is … See more Renal clearance can be measured with a timed collection of urine and an analysis of its composition with the aid of the following equation (which follows directly from the derivation of (10b)): $${\displaystyle K={\frac {C_{U}\cdot Q}{C_{B}}}}$$ See more For substances that exhibit substantial plasma protein binding, clearance is generally dependent on the total concentration (free + protein-bound) and not the free concentration. Most plasma substances have primarily their free … See more • Augmented renal clearance • Creatinine clearance • Kt/V • Pharmacokinetics See more • Sharifi M, Ghafourian T (January 2014).
