Biostatistics For Dummies. A PK/PD study also acquires many other measurements that indicate the drug’s effects on the body, often at the same (or nearly the same) sampling time points as for the PK samples. These PD measurements include: Blood and urine sampling for other chemicals that would be affected by the drug: For example,

PK/PD modeling is related to the field of pharmacometrics. There are a variety of PK/PD modeling approaches to describe exposure-response relationships. PK/PD relationships can be described by simple equations such as linear model, Emax model or sigmoid Emax model.

Understanding the PK/PD behavior of a drug helps design the dose, route, and schedule of administration to maximize effectiveness while reducing adverse effects. Bioanalytical testing methods are used to determine concentration time profiles of the drug and metabolites in biological fluids, providing information necessary for PK analysis.

PK/PD. In vitro toxicology is the study of the effects of chemicals and drugs on cultured bacteria or mammalian cells.Drug effect can be both time and concentration dependent and these parameters can be species specific. In the case of antibiotic development, there have not been effective tools for examining the effects of both time and concentration in an in vitro model, mimicking human kinetics.

The study of PK/PD and Disease Progression relationships can be of considerable value in understanding drug action, summarizing extensive data, building a knowledge repository, finding optimal dosing regimens, and in making predictions under new circumstances. More advanced PK/PD models have evolved into Systems Pharmacology.


Shinju Obara, Talmage D. Egan, in Pharmacology and Physiology for Anesthesia, 2013. Variability. Another major shortcoming in applying PK-PD models clinically is that standard simulations using PK-PD model parameters do not typically include an expression of variability in the PK-PD predictions.

in PK/PD modelling. The reason is that concentration of a drug is relatively easy to measure from a blood sample and at the same time concentration is a key factor when modelling both positive and negative e ects of a drug. Con-centration is calculated as C = A V (1) where A is amount of drug and V is the volume of distribution. The amount
