What is the pharmacokinetics meaning?
What is the pharmacokinetics meaning?
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 the definition of pharmacodynamics quizlet?
Define Pharmacodynamics. the study of the biochemical and physiologic effects of drugs on the function of living organisms and thier component parts (how it works in the body)
What are the 4 steps of pharmacokinetics quizlet?
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 pharmacokinetics and pharmacodynamics definition?
Pharmacokinetics is the study of what the body does to the drug, and Pharmacodynamics is the study of what the drug does to the body.
What is pharmacokinetics and why is it important?
Pharmacokinetics is a science that studies how certain substances affect a living organism when administered. This particular science determines what happens to a drug from the time it is administered throughout its circulation within the body and to the moment when it is ultimately eliminated from the body.
What is the correct definition for pharmacodynamics?
Pharmacodynamics is the study of a drug’s molecular, biochemical, and physiologic effects or actions. It comes from the Greek words “pharmakon,” meaning “drug,” and “dynamikos,” meaning “power.”
What’s the difference between pharmacokinetics and pharmacodynamics?
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’.
How does pharmacodynamics different from pharmacokinetics?
The difference between pharmacokinetics (PK) and pharmacodynamics (PD) can be summed up pretty simply. Pharmacokinetics is the study of what the body does to the drug, and Pharmacodynamics is the study of what the drug does to the body.
What 4 factors affect pharmacokinetics?
Pharmacokinetics can vary from person to person and it is affected by age, gender, diet, environment, body weight and pregnancy, patient’s pathophysiology, genetics and drug- drug or food-drug interactions. Drug therapy is impacted by factors that affect pharmacokinetics and pharmacodynamics.
