What pharmacokinetic means?

Listen to pronunciation. (FAR-muh-koh-kih-NEH-tix) The activity of drugs in the body over a period of time, including the processes by which drugs are absorbed, distributed in the body, localized in the tissues, and excreted.

What is pharmacokinetic and pharmacodynamic?

In simple words, pharmacokinetics is 'what the body does to the drug'. Pharmacodynamics describes the intensity of a drug effect in relation to its concentration in a body fluid, usually at the site of drug action. It can be simplified to 'what the drug does to the body'.

What are the 4 pharmacokinetic processes?

Think of pharmacokinetics as a drug's journey through the body, during which it passes through four different phases: absorption, distribution, metabolism, and excretion (ADME).

What is the function of pharmacokinetics?

Pharmacokinetics is a branch of pharmacology that describes the processes of absorption, distribution, metabolism, and excretion of a drug by the body as a mathematical function of time and concentration (Cannon, 1996; Mager and Jusko, 2008; Dash et al., 2010).

What is pharmacokinetics Slideshare?

Definitions • Pharmacokinetics – The process by which a drug is absorbed, distributed, metabolized and eliminated by the body – Quantitative study of drug movement in, through and out of the body. –

Why is it important to understand pharmacokinetics?

Some of the most important pharmacokinetic properties to understand during pre-clinical testing include distribution, absorption, metabolism, and excretion. ... Pharmacokinetic testing can ensure that drugs do not fail during clinical trials for reasons that could have been predicted and avoided.

What is pharmacology and pharmacokinetics?

Clinical pharmacology is the study of the interactions between drugs and the human body. Pharmacokinetics and pharmacodynamics are two broad divisions within clinical pharmacology. ... Regulatory agencies are also responsible for ensuring that all available drugs are effective and safe for human use.

What is pharmacokinetics NCBI?

Pharmacokinetics (PK) is the study of how the body interacts with administered substances for the entire duration of exposure (medications for the sake of this article). This is closely related to but distinctly different from pharmacodynamics, which examines the drug's effect on the body more closely.

How is pharmacodynamics best defined?

Pharmacodynamics is defined as the response of the body to the drug. It refers to the relationship between drug concentration at the site of action and any resulting effects namely, the intensity and time course of the effect and adverse effects.

How do you study pharmacokinetics?

A standard pharmacokinetic study is the conventional method for evaluating the pharmacokinetics of a drug in human subjects. In such a study, subjects are given a single dose or repeated doses of an investigational drug. Then, blood and urine samples are collected in compliance with a fixed schedule.

What is Pharmacokinetics absorption?

Drug absorption is a pharmacokinetic parameter that refers to the way a drug is absorbed from a pharmaceutical formulation into the bloodstream. Image Credit: By NOOMEANG / Shutterstock. Several factors can affect the absorption of a drug into the body. These include: physicochemical properties (e.g. solubility)

What is plasma half-life of drug?

The half-life of a drug is the time taken for the plasma concentration of a drug to reduce to half its original value. Half-life is used to estimate how long it takes for a drug to be removed from your body.

What are the pharmacokinetic parameters?

The pharmacokinetic characteristics can be quantitatively expressed by its parameters, such as the elimination rate constant (denoted as K), half-life (t _1/2), apparent volume of distribution (V _d) and total clearance rate (CL).

What is pharmacokinetics in distribution?

Distribution in pharmacology is a branch of pharmacokinetics which describes the reversible transfer of a drug from one location to another within the body. ... Each organ or tissue can receive different doses of the drug and the drug can remain in the different organs or tissues for a varying amount of time.

What do you mean by agonist?

Agonist: A substance that acts like another substance and therefore stimulates an action. Agonist is the opposite of antagonist. Antagonists and agonists are key players in the chemistry of the human body and in pharmacology.

What represents a pharmacokinetic phase?

This phase describes the time course and disposition of a drug in the body, based on its absorption, distribution, metabolism and elimination.

What does affinity mean in pharmacology?

Affinity can be defined as the extent or fraction to which a drug binds to receptors at any given drug concentration or the firmness with which the drug binds to the receptor.
