Clinical Pharmacokinetics is a peer-reviewed medical journal published by Adis International (Springer Nature) that covers topics related to pharmacokinetics.According to the Journal Citation Reports, the journal has a 2023 Impact Factor™ of 4.6 ranked 77 of 277 journals in the Pharmacology & Pharmacy category [Clarivate Analytics]; 2023 CiteScore™ of 8.8 ranked 81 of 272 journals in the ...
Explore the concept of PK/PD models, which integrate pharmacokinetics and pharmacodynamics to optimize drug dosing and efficacy.
The first pharmacokinetic model described in the scientific literature [2] was in fact a PBPK model. It led, however, to computations intractable at that time. The focus shifted then to simpler models, [3] for which analytical solutions could be obtained (such solutions were sums of exponential terms, which led to further simplifications.)
Rowland has published over 270 research articles in international peer-reviewed journals, and over 60 book chapters and conference reports. He co-authored with Thomas Tozer two standard textbooks: Clinical Pharmacokinetics and Pharmacodynamics: Concepts and Applications, now in its 5th edition, and Essentials of Pharmacokinetics and Pharmacodynamics.
Pharmacokinetics is based on mathematical modeling that places great emphasis on the relationship between drug plasma concentration and the time elapsed since the drug's administration. Pharmacokinetics is the study of how an organism affects the drug, whereas pharmacodynamics (PD) is the study of
Pharmacokinetics simulation gives an insight to drug efficacy and safety before exposure of individuals to the new drug that might help to improve the design of a clinical trial. Pharmacokinetics simulations help in addition in therapy planning, to stay within the therapeutic range under various physiological and pathophysiological conditions ...
The use of trapezoidal rule in AUC calculation was known in literature by no later than 1975, in J.G. Wagner's Fundamentals of Clinical Pharmacokinetics. A 1977 article compares the "classical" trapezoidal method to a number of methods that take into account the typical shape of the concentration plot, caused by first-order kinetics. [8]
In clinical practice, this means that it takes 4 to 5 times the half-life for a drug's serum concentration to reach steady state after regular dosing is started, stopped, or the dose changed. So, for example, digoxin has a half-life (or t 1 / 2 ) of 24–36 h; this means that a change in the dose will take the best part of a week to ...
