Linear pharmacokinetics (but not not pharmacodynamics) describes a linear system, in which the rate of transfer of drug or other chemical from one compartment to another is directly proportional to the total mass of the drug in this compartment. 2012-11-09 · Nonlinear pharmacokinetics (in other words, time or dose dependences in pharmacokinetic parameters) can arise from factors associated with absorption, first-pass metabolism, binding, excretion and biotransformation. Nonlinearities in absorption and bioavailability can cause increases in drug concentrations that are disproportionately high or low A linear system approach to analyzing the pharmacokinetics of carbon tetrachloride in the rat following repeated exposures of 8 and 11.5 hr/day.Arch.

The half-life will remain constant, irrespective of how high the concentration.

2016-10-19 In linear pharmacokinetics, clearance is a constant for a given drug: (15.2) Thus, the bioavailability (F) of a drug can be assessed from the dose-normalized AUC. Absolute bioavailability of an extravascular dose (FPO) is determined by comparing its dose-normalized AUC to that after intravenous administration (F IV = … Non-linear pharmacokinetic models, as opposed to linear pharmacokinetic models differ in some very critical areas. When the concentration that results from the dose is proportional to that dose and the rate of elimination of the drug is proportional to the concentration, the drug is said to exhibit linear pharmacokinetics as shown below. เมื่อเราเพิ่ม dose ของยาเป็นสองเท่า โดยปกติแล้วถ้าเป็น linear pharmacokinetics ก็จะทำให้ความเข้มข้นของยาเพิ่มขึ้นเป็นสองเท่าตามไปด้วย แต่ถ้าเป็นในกรณี non-linear pharmacokinetics ควาาเข้มข้นจะไม่เพิ่มเป็น The binding of drugs to plasma constituents, blood cells and extravascular tissue may exhibit concentration dependence.

Apply nonlinear pharmacokinetics to describe steady-state plasma concentrations following parenteral and/or oral phenytoin therapy. Introduction Pharmacokinetics provides a mathematical basis to assess the time course of drugs and their effects in the body. It enables the following processes to be quantiﬁed: Absorption Distribution Metabolism Excretion 1988-08-01 Even when secretion is saturated, filtration continues to increase linearly with plasma drug concentration. The extent to which saturation of renal secretion results in non-linear pharmacokinetics depends on the relative importance of secretion and filtration in the drug's elimination. 2016-10-19 In linear pharmacokinetics, clearance is a constant for a given drug: (15.2) Thus, the bioavailability (F) of a drug can be assessed from the dose-normalized AUC.
