Pharmacology is the study of drugs and their actions on the body.

Pharmacodynamics refers to the mechanisms of drug action…the study of how a drug affects our bodies.
The majority of drugs elicit a response depending on how they interact with a particular protein, which happens through a receptor protein embedded in the cell membrane, or inside the cell within the cytoplasm or in the nucleus.
Sometimes a drug acts as a ligand for a receptor.
A drug may be:
Drug Potency: the strength of a drug at a particular dosage or the amount of a drug required to produce a particular effect. Potency can also be described as the affinity of a drug for a receptor (high affinity = small amount of drug needed).
Drug Efficacy: maximum effect that can be achieved by a drug. Efficacy can also be described as the effect the drug has on the receptor and how well it acts as an agonist or an antagonist.
