Involved with the absorption, distribution, metabolism, and excretion of drugs.
The mathematical analysis of the time courses of absorption, distribution, and elimination of drugs.
The study of the process and rates of drug distribution, metabolism, and disposition in the organism.
A branch of pharmacology dealing with the reactions between drugs or synthetic food ingredients
and living structures (e.g., tissues, organs). The study of the:
- absorption—transport of the pharmaceutical or food ingredient into the bloodstream (e.g., from the intestinal tract, in the case of food ingredients)
- distribution—initial physical disposition/behavior of the substance in the body after the substance enters the body. For example, does the substance preferentially concentrate in the fat cells of the body? etc.
- metabolism—breakdown of the substance (if breakdown does occur) into other compounds, and ultimate disposition of those compounds (or the original substance, if breakdown does not occur). For example, some pharmaceuticals break down into smaller compound(s); one of which then acts upon the relevant body cells (e.g., to relieve pain, lower blood pressure, etc.).
- elimination—the speed and thoroughness with which the substance is excreted or otherwise removed from the body.
In short, pharmacokinetics deals with what happens to a substance that is introduced into a living system. For example, how quickly it is broken down, to what intermediates and metabolites it is broken down, and what the pathway of this breakdown is.
The study of how medicinal substances are absorbed, moved, distributed, metabolised and excreted.
The study of what happens to drugs once they are in the body.
Referring to a property of a drug which has an effect over a period of time.
The study of how the body reacts to drugs over a period of time.
The way in which a drug interacts with the body.
The study of how the body handles drugs; that is, the manner in which drugs are absorbed, distributed, metabolized, and excreted.
Study of the action of drugs in the body, including the method and rate of absorption and excretion, the duration of effect, and other factors.
The study of drug levels in the body over a period of time. Pharmacokinetics addresses several topics, including a drug’s metabolism, the duration of its action, the time required for it to be absorbed, and how it is distributed throughout the body and then excreted or eliminated.
The way in which the body deals with a drug. This includes the drug’s absorption, distribution in the tissues, metabolism, and excretion.
The study of the metabolism and action of drugs with particular emphasis on the time required for absorption, duration of action, distribution in the body, and method of excretion.
The phrase utilized to depict the body’s interactions with a medication. This encompasses the process through which the drug is assimilated into the bloodstream, its dissemination to various bodily tissues, and its metabolism for eventual elimination from the body.
