Definition of Pharmacology ‒ compendium of concepts and meanings
1. Definition of PharmacologyPharmacology (in Greek, pharmacon (φάρμακον), drug, and logos (λόγος), science) is the science that studies the origin, the actions and the properties of chemicals on living organisms. In a narrower sense, is considered the pharmacology study of drugs, is that those have either beneficial or toxic effects. Pharmacology has clinical applications when substances are used in the diagnosis, prevention and treatment of a disease or for relief of their symptoms.
You can also talk of Pharmacology as the unified study of the properties of chemical substances and living organisms and all aspects of their interactions, oriented towards the treatment, diagnosis and prevention of diseases.
Pharmacology as a science encompasses the knowledge of the history, origin and use of drugs, as well as their physical and chemical properties, associations, effects of the drug on the body, and impact of the Agency on the drug (absorption, distribution, biotransformation and excretion). Another application of Pharmacology takes place in agriculture to accelerate plant growth and eliminate pests.
Pharmacology is one of pharmaceutical sciences major, being a chemical application of a mixture between molecular biology, Physiology/pathophysiology, cell biology and biochemistry. Although Pharmacology stand out from other pharmaceutical sciences, is not more important than the others (pharmaceutical chemistry, pharmacognosy, pharmaceutical Botany, phytochemistry, etc.). All of them are mutually supportive and it is very rare that one work isolated from the others.
2 Concept of PharmacologyHe is understood by Pharmacology to the science dedicated to the study and analysis of different substances on the human body or animal. These substances, known as drugs, are administered artificially, and although they can exist in the body, the pharmacology is dedicated to studying the effects of those that are managed externally (i.e. by via oral, intravenous, etc.). Pharmacology is an important branch of medicine since professionals based on her possible previously plotted Diagnostics and solutions according to the needs and particularities of each case.
The term drug derives from the Greek word pharmakon meaning drug or medication. With this in mind, we can easily understand the pharmacology is the science which includes analysis and detailed study of all medications, drugs and chemical substances that exist both man-made as existing in nature that have some kind of effect on human or animal bodies.
Based on the knowledge that Pharmacology sets on one type of substance, for example the buscapina, medicine can then act prescribing it in the cases in which those symptoms which mitigates this type of substance. Pharmacology also develops knowledge about the best methods of Administration for each substance (taking it to do with the way in which will be more easily assimilated by the body), how that substance will be distributed in the bloodstream, how it will be assimilated by the metabolism of each organism (and here is where the particularities of each case must be taken into account) and how it will be finally excreted that anything that is not used by the body. The theory of Pharmacology can sometimes differ from what happens in practice precisely from the issues or specific elements of each case.
3 Meaning of PharmacologyAccording to its etymology, the word Pharmacology comes from the Greeks "Pharmacon" meaning "Drug" and "Logos" which means "Science". Before proceeding, it is necessary to briefly define what is a drug, it is because of a chemical substance, highly synthesized in order to reduce any characteristic of a disease condition. The drugs are widely diversified, established since prehistoric times and with a purely natural history, drugs are cures for diseases.
So, what is Pharmacology? It is a science that analyzes and decodes the most relevant aspects of chemistry in order to be able to produce strains of diseases molecular structures in the form of retrovirus, order so to combat the symptoms and disease conditions. Pharmacology is a science of broad spectrum that analyzes chemical elements, their combinations and their effects on living beings, for the charitable purpose of always finding solutions of disease. Pharmacology uses methods of research and experiments, based on the foundations laid down by the disease for which are designed, this view allows Pharmacology cope all possible resources to deal with any anomaly or variation in the disease.
The symptoms of the disease are identified if it is infectious or viral, then any plant or biological organism containing substances that function as controller or dominant disease in its composition is located in the biological nature. A clear example of this procedure is the development of penicillin, this broad spectrum antibiotic, famous for the amount of infections that are controlling it was obtained thanks to the studies of a got mildew in a rotten bread, these studies developed in the last century have evolved thanks to the microbiology and cell technology. Pharmacology also studies the way in which drugs Act on the metabolism of human beings, that's why that are of vital importance to discover the correct ways in how the body must absorb drugs, because the answers that the Agency can give depending on the manner in which they are applied may be relevant for the body.
4. What is PharmacologyPharmacology is the science that deals with drugs or drugs.
Drug: Any substance is inserted into the body interacts with him, giving rise to a benefit or prejudice, based on this we will talk of drug substance or drug if what you see is profit, or talk about toxic if the result is bad.
Pharmacology is the study of the processes that suffers a drug since it is administered until removed, understanding why the pharmacodynamics, pharmacokinetics, toxicology.
According to Pharmacology study drugs with beneficial therapeutic action or study of drugs in general, we can talk about pure Pharmacology when you study the interactions of drugs with the living being without taking into account the action of the drug and applied Pharmacology, when studying drugs that return a beneficial effect on the living being.
Pharmacology function of the drugs studied in terms of action on the different systems of the body can in turn divided. Thus spoken of Pharmacology of the nervous system, the digestive system Pharmacology, pharmacology of cardiovascular system, pharmacology of the excretory, pharmacology of the skin...
The origin of the drugs can be vegetable (if the drug - active principle - comes from a plant), animal (hormones), synthetic. Synthetic drugs pose a greater number in front of animal or vegetable origin.
