Pharmacokinetics (from Ancient Greek pharmakon "drug" and kinetikos "moving, putting in motion"; see chemical kinetics), sometimes abbreviated as PK, is a branch of pharmacology dedicated to describing how the body affects a specific substance after administration. [1]
Distribution in pharmacology is a branch of pharmacokinetics which describes the reversible transfer of a drug from one location to another within the body.. Once a drug enters into systemic circulation by absorption or direct administration, it must be distributed into interstitial and intracellular fluids.
Pharmacokinetics – what happens to the drug while in the body. This involves the body systems for handling the drug, usually divided into the following classification: Absorption – the processes by which the drug move into the bloodstream from the site of administration (e.g. the gut)
The four letter stands for descriptors quantifying how a given drug interacts within body over time. The term ADME was first introduced in the 1960s, and has become a standard term widely used in scientific literature, teaching, drug regulations, and clinical practice. [1] ADME, describes the disposition of a pharmaceutical compound within an ...
The action of drugs on the human body (or any other organism's body) is called pharmacodynamics, and the body's response to drugs is called pharmacokinetics. The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way.
Pharmacodynamics is sometimes abbreviated as PD and pharmacokinetics as PK, especially in combined reference (for example, when speaking of PK/PD models). Pharmacodynamics places particular emphasis on dose–response relationships , that is, the relationships between drug concentration and effect. [ 1 ]
In broad terms, pharmacodynamics discusses the chemicals with biological receptors, and pharmacokinetics discusses the absorption, distribution, metabolism, and excretion (ADME) of chemicals from the biological systems. Pharmacology is not synonymous with pharmacy and the two terms are frequently confused.
Pharmacokinetics The processes (in a living organism) of absorption, distribution, metabolism, and excretion of a drug or vaccine. (NLM) Phase I clinical trials. The first step in testing a new treatment in humans. These studies test the best way to give a new treatment (for example, by mouth, intravenous infusion, or injection) and the best dose.
