Pharmacokinetic median parameters of a bolus dose of 1 The distribution of artemether was described by a two-compartment model with a rapid absorption and elimination through metabolism to dihydroartemisinin. This article describes the experimental set-up and pharmacokinetic modeling of of [(11)C]verapamil was well described by a two-compartment model. av AL VAN STEVENINCK · 1996 · Citerat av 96 — Estimates of the elimination half-lives of bretazenil were obtained by fitting a two compartment model to the plasma drug concentration-time curves. Elimination.

The two-compartment model assumes that, at t = 0, no drug is in the tissue compartment. After an IV bolus injection, drug equilibrates rapidly in the central compartment.

Assumptions In compartment models, 2010-05-28 Pharmacokinetic two-compartment model Pharmacokinetics refers to the rate and extent of distribution of a drug to different tissues, and the rate of elimination of the drug. Pharmacokinetics can be reduced to mathematical equations, which describe the transit of the drug throughout the body, a net balance sheet from absorption and distribution to metabolism and excretion.
