Pharmacology is understood to be that science that is dedicated to the study and analysis of different substances on the human or animal organism. These substances, known as drugs, are administered artificially and although they may exist in the body, pharmacology is dedicated to studying the effects of those that are administered from the outside (that is, orally, intravenously, etc.) . Pharmacology is an important branch of medicine since on it the professionals base the possible solutions to the previously outlined diagnoses and according to the needs or particularities of each case.
The term drug comes from the Greek term phármakon which means drug or medicine. Taking this into account, we can easily understand that pharmacology is the science that includes the analysis and detailed study of all medicines, drugs and chemical substances that exist both created by man and existing in nature that have some kind of effect on the human or animal organisms.
Based on the knowledge that pharmacology establishes about a type of substance, for example, buscopan, medicine can then act by prescribing it in cases in which those symptoms that this type of substance mitigates are present. Pharmacology also develops knowledge about the best methods of administration for each substance (having this to do with the way in which it 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 this is where the particularities of each case must be taken into account) and how finally all that element that is not used by the organism will be excreted. The theory of pharmacology can sometimes differ from what happens in practice precisely on the basis of the specific questions or elements of each case.
