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.
Common examples of drugs that work in this way are antacids and laxatives. [ 2 ] In contrast, a mode of action (MoA) describes functional or anatomical changes, at the cellular level, resulting from the exposure of a living organism to a substance.
Topics of pharmacodynamics. Pharmacodynamics (PD) is the study of the biochemical and physiologic effects of drugs (especially pharmaceutical drugs).The effects can include those manifested within animals (including humans), microorganisms, or combinations of organisms (for example, infection).
Pharmacology can also focus on specific systems comprising the body. Divisions related to bodily systems study the effects of drugs in different systems of the body. These include neuropharmacology, in the central and peripheral nervous systems; immunopharmacology in the immune system.

Therefore, the chemical characteristics of a drug will determine its distribution within an organism. For example, a liposoluble drug will tend to accumulate in body fat and water-soluble drugs will tend to accumulate in extracellular fluids. The volume of distribution (V D) of a drug is a property that quantifies the extent of its distribution ...
In the process, metabolites, or byproducts, of the drug are produced, which can linger in our blood, urine (and even in our hair) for long after the initial effects of the drug are felt.
Physiological agonism describes the action of a substance which ultimately produces the same effects in the body as another substance—as if they were both agonists at the same receptor—without actually binding to the same receptor.
