DRUG RECEPTORS Meaning and
Definition
-
Drug receptors are a crucial component of the human body's intricate communication system that facilitates the interaction between drugs and specific target sites. These receptors are proteins located on the surface or within the cells of target tissues or organs. They possess the remarkable ability to bind with specific drugs or molecules, facilitating the transmission of signals and initiating a chain of responses within the body.
Drug receptors play a pivotal role in various physiological processes and serve as key regulators of chemical signaling. They act as gatekeepers, receiving signals from drugs and relaying them to the cellular machinery, triggering a cascade of events that ultimately produce pharmacological effects. When a drug binds to its specific receptor, it can either mimic the action of an endogenous compound or inhibit its effects, modulating the function of the target tissue or organ.
These receptors are highly specific and selective, typically recognizing a particular class of drugs or molecules. They exhibit affinity, the ability to bind with the drug, and efficacy, the ability to initiate a response. The interaction between a drug and its receptor is often reversible, allowing for transient effects or prolonged actions, depending on factors such as drug concentration and receptor density.
Understanding drug receptors is fundamental in the fields of pharmacology and medicine, as it enables researchers to design drugs that can selectively target specific receptors to achieve desired therapeutic effects. The study of drug receptors encompasses various techniques, including molecular biology, biochemistry, and structural biology, aiming to elucidate their structure, function, and mechanisms of action.

Etymology of DRUG RECEPTORS
The etymology of the term "drug receptors" can be broken down as follows:
1. Drug: The term "drug" originates from the Middle English word "drogge", which came into English from Old French "drogue" meaning "medicine, chemical substance". It ultimately derives from the Dutch word "droge", which means "dry". Originally, the word referred to any dried substance used in medicine, but eventually came to refer specifically to substances with pharmacological effects.
2. Receptors: The term "receptor" in the context of biochemistry and pharmacology refers to a protein molecule that receives signals from within the cell or from the outside environment, leading to a specific biochemical response. The word "receptor" comes from the Latin word "receptus", which is the past participle of "recipere" meaning "to receive" or "to take in".
